X1. KERNEL DEFINITIONS
X
X1.1 Vocabulary listing parameters (File: kernel.c)
X
XThe column and line width used by "words" may be altered by changing
Xthe lines:
X
X#define COLUMNWIDTH 15
X#define LINEWIDTH 75
X
X
X1.2 Set of search vocabularies (File: kernel.c)
X
XThe set of search vocabularies, "context", is realized as a vector.
XThe maximum number of vocabularies in is defined by:
X
X#define CONTEXTSIZE 32
X
XAn error will occur it the set is filled. No checking is currently
Xperformed.
X
X
X1.3 Lookup cache (File: kernel.c)
X
XThe lookup function in the kernel is supported by a simple cache.
XA hash function (see below) is used to map a string into the cache
Xand there, if possible, find the entry. The size of the cache
Xis given by:
X
X#define CACHESIZE 256
X#define hash(s) ((s[0] + (s[1] << 4)) & (CACHESIZE - 1))
X
XThe hash function is tailored for the current cache size and thus
Xspecial care must be taken when altering these.
X
X
X1.4 Internal structures (File: kernel.c)
X
XThe "pad" and the "tib" may be changed by altering:
X
X#define PADSIZE 84
X#define TIBSIZE 256
X
X
X1.5 Word alignment (File: kernel.h)
X
XAlignment of threaded code and data structures are performed by the
Xmacro:
X
X#define align(p) p = (long *) ((long) ((char *) p + 3) & -4)
X
XThis macro currently aligns to word (long) boundaries and is used by
X"colon" and "create".
X
X
X1.6 Function casting (File: kernel.h)
X
XSome compilers might not like the current definition of casting of
Xa function to a long number in the entry structure. To reduce rewriting
Xa macro is used:
X
X#define SUBR(x) ((long) (void (*) ()) (x))
X
XThis macro is used by the entry generators (see kernel.h). Some
Xcompilers will not allow this and thus will require that the primitive,
Xi.e. the C-level subroutines, are bound at run-time. This code is
Xnot included.
X
X
X1.7 Initialization of the kernel (File: kernel.c)
X
XThe initialization function for the kernel requires five parameters.
XThe two first allows the application such as forth.c to extend the
Xbasic forth vocabulary by giving the first and last entry in the
Xapplication vocabulary. The three following parameters specify the
Xsize of the foreground task, the forth interpreter. See the file
Xforth.c for an example.
X
X
X2. IO MANAGEMENT
X
X2.1 File and path name size (File: io.c)
X
XThe maximum length of a file or path name is defined as:
X
X#define FILENAMESIZE 128
X#define PATHNAMESIZE 128
X
XThese length are not test for currently. An error may occur if
Xa file or path name is longer than the given sizes.
X
X
X2.2 File buffer stack (File: io.c)
X
XThe io management package implements a stack of input file buffers to
Xallow loading of files from within other files etc. The maximum depth
Xof this stack is defined as:
X
X#define FSTACKSIZE 32
X
XThe depth should be chosen to the maximum number of open files.
X
X
X2.3 Set of loaded files (File: io.c)
X
XThe file loading mechanism automatically looks if the file already
Xhas been opened. The set of opened files is maintained as a vector.
XThe maximum number of loaded files is:
X
X#define INFILESSIZE 64
X
XThe vector contains the fully expanded names of the loaded files.
XAn error may occur if this limit is succeeded. It is not checked for
Xcurrently.
X
X
X2.4 Set of paths (File: io.c)
X
XThe io packages also maintains an ordered collection of paths which
Xare used to expand file names with when search for the file. The
Xmaximum size of this collection is defined by:
X
X#define PATHSSIZE 64
X
XThis collection is automatically appended by the $TILEPATH environ-
Xment variable when the io package is initiated.
X
X
X2.5 White space (File: io.h)
X
XThe definition of "white" space is defined as:
X
X#define ISSPACE(c) ((c) <= ' ')
X
XThis eliminates space and any control characters. Some application
Xmight want to redefine this.
X
X
X2.6 Non-blocking read operation (File: io.c)
X
XTo achieve multi-tasking during input wait the input package function
X"io_fillbuf" uses a non-blocking read operation. Some environments
Xdo not support this. Thus this may require re-implementation.
X
XTo check if the read operation was an success the error number
Xvariable is used ("errno"). Some environments do not include it
Xin the include file thus the below line is needed:
X
Xextern int errno;
X
XThis is available in SUN include files.
X
X
X3. ERROR MANAGEMENT
X
X3.1 Signals (File: error.c)
X
XError handing is realized using two basic mechanisms; first signals from
Xthe execution environment and second by user defined exceptions in
Xthe kernel (high level code).
X
XThe signal message table and the appropriate operations, "error_restart",
Xor "error_fatal", may have to be changed to give the right performance.
X
XPlease see these functions and "error_initiate" where the actual binding
Xof signals and actions is performed.
X
X
X4. MEMORY MANAGEMENT
X
X4.1 Memory allocation (File: memory.c)
X
XCurrently memory for the dictionary, strings, entries, and task blocks
Xare allocated using "malloc".
X
XThe size of the dictionary is determined when calling the initialization
Xfunction in the memory management package, "memory_initiate". The
Xcurrent size is defined as:
X
X#define DICTIONARYSIZE 128L * 1024L
X
XAnd may be too large for smaller machines. Please see the file: forth.c.

XDESCRIPTION
X Kernel compiler definitions isolated to a separate vocabulary
X to minimize dependencies and increase portability.
X
Xcompiler ( -- )
X Vocabulary containing the compilation word set. Compiler
X support, compiled words and threading primitives.
X
X(branch) ( -- ) compilation
X Performs the run-time action of branching in threaded code.
X Literal succeeding this word contains a relative address to
X the next thread.
X
X(?branch) ( flag -- ) compilation
X Performs the run-time action of conditionally branching in
X threaded code. If the flag is zero a branch is performed
X using a literal succeeding this word else the literal is
X skipped.
X
X(do) ( end start -- ) compilation
X Performs the run-time action of initializing for a loop block.
X Moves the two parameters, "end" and "start", to the return
X stack and a pointer to the relative address literal succeeding
X this word so that "leave" may be performed in any section of
X the looped block.
X
X(?do) ( end start -- ) compilation
X Performs the run-time action of initializing for a loop block if
X the "start" and "end" index are not equal else skips the block.
X Moves the two parameters, "end" and "start", to the return
X stack and a pointer to the relative address literal succeeding
X this word so that "leave" may be performed in any section of
X the looped block.
X
X(loop) ( -- ) compilation
X Performs the run-time action of incrementing the loop index and
X checking it against the upper limit for the loop. If the index
X is still within the loop limit a branch is performed back to the
X beginning of the loop. The branch offset is stored in-line
X directly after the "(loop)" thread.
X
X(+loop) ( increment -- ) compilation
X Performs the same action as "(loop)" but uses the top of stack
X value as the increment of the loop index. Checks if the loop
X limit has been exceeded.
X
X(literal) ( -- literal) compilation
X Pushes the in-line constant following the threaded code onto
X the parameter stack.
X
X(.") ( -- string) compilation
X Pushes the in-line string pointer following the threaded code
X onto the parameter stack.
X
X(abort") ( flag -- ) compilation
X Performs the run-time action of checking the error flag and
X if non-zero, true, aborts the current computation. Uses an
X in-line string to display an abort message.
X
X(;) ( -- ) compilation
X Performs the run-time action of returning from a colon definition.
X
X(does>) ( -- ) compilation
X Performs the run-time action of returning from the current colon
X definition and setting the code type of the last defined entry
X to be the code following "(does>)" thus giving it the right
X run-time action.
X
Xthread ( ptr -- )
X Used to create threaded code in the dictionary area. Allows code
X to be written without considering the threading principle.
X
Xunthread ( ptr1 -- ptr2)
X Given a reference to threaded code returns an unthreaded entry
X pointer.
X
X>mark ( -- marker) compilation
X Allocates space for a branch offset and marks it for forward
X resolving.
X
X<mark ( -- marker) compilation
X Marks the current position in the compilation code stream as
X a position for backwards branch.
X
X>resolve ( marker -- ) compilation
X Resolves a forward branch offset.
X
X<resolve ( marker -- ) compilation
X Allocates space for and calculates a backward branch offset.

XWARNING
X Code written using this word set is not directly portable to
X other forth environments.

XDESCRIPTION
X Forth level debugger package. Allows basic black-box tracing of
X colon definitions, break on function call and profiling of function
X calls. The debugger is built on a general advice package so that
X it may easily be extended with addition debugging functions. The
X advice concept is a function may be asked for advice to handle a
X colon definition. The trace advice function wraps the function
X call in printing of the stack status and the name of the function.
X
Xdebugger ( -- )
X Vocabulary containing the debugger definitions.
X
XADVICE ( -- ) private
X The advice structure type. Allows general handling of execution
X of code definitions.
X
X+block ( advice -- block) private
X Access field to code block of advice colon definition. Stored
X as a pointer to threaded code.
X
X+entry ( advice -- entry) private
X Access field to entry with advice block. Allows access of entry
X fields such as name, link, etc. Stored as a pointer to an entry.
X
X+advice ( advice -- advice) private
X Access field to advice function which is called to handle the
X code block. The advice function is call with execute thus it
X is a pointer to an entry. Three predefined advice functions
X are available for profiling, tracing and break points.
X
X+profile ( advice -- profile) private
X Access field to counter for number of function calls. Basic
X profiling information. Updated by the advice primitives.
X
X[advice] ( advice -- ) private
X Management function to allow interception of function call and
X calling of advice function.
X
X[colon] ( advice -- ) private
X Primitive advice function call for normal function call and
X increment of profiling counter.
X
X[trace] ( advice -- ) private
X Primitive advice function for black-box tracing of function
X calls. The entry and exit of the function call are printed
X together with the name of the function and the status of the
X stack.
X
X[break] ( advice -- ) private
X Primitive advice function which allows a simple break point
X command loop. The commands are currently: a(bort), c(ontinue),
X e(xecute), p(rofile) and r(eturn). The e(xecute) command calls
X the function and returns to the break point command loop.
X The e(xecute) performs the function in the normal manner
X without returning to the command loop. The p(rofile) command
X print the profile counter for the broken function. And last
X the r(eturn) command exits the command loop without performing
X the function.
X
Xtail-recurse ( -- ) compilation immediate
X Redefinition of the tail recursion compilation word to make it
X work correctly in this context.
X
X?advice ( entry -- flag)
X Verifies that the entry passed as a parameter is an advice
X function.
X
Xadvice ( action -- )
X Used in the form:
X ' <advice-action> advice <advice-colon-definition>
X Make the parameter action the advice action for an advice
X colon definition. The colon definition is verified before
X the assignment is performed. The advice action should be
X a function which receives an advice block and performs some
X action on it. Resets the profile information.
X
Xcolon ( -- )
X Used in the form:
X colon <advice-colon-definition>
X To make an advice colon definition a "normal" function again.
X An error message is given if the succeeding symbol is not of
X correct type.
X
Xtrace ( -- )
X Used in the form:
X trace <advice-colon-definition>
X To make an advice colon definition a traced function. An
X error message is given if the succeeding symbol is not of
X correct type.
X
Xbreak ( -- )
X Used in the form:
X break <advice-colon-definition>
X To make an advice colon definition function with a break point.
X An error message is given if the succeeding symbol is not of
X correct type.
X
X.r ( n w -- )
X Prints the number, "n", right aligned in a field with width, "w".
X
X.profile ( -- )
X Scans through the vocabulary and prints the profile information
X for advice functions. Prints the number of calls and the name
X of the functions.
X
X: ( -- )
X Redefinition of "colon" to allow easy debugging of "any" code
X definitions without rewriting.

X Compiled by "{" to perform the run-time action of building
X the argument and local variable frame. These are built on the
X parameter stack to minimize data movement. The frame consists
X of the arguments and stack area for the local variables. The
X old frame pointer and the top of stack are saved on the return
X stack so that the stack and the frame pointer may be restored
X after a definition using this extension.
X
X(unlink) ( frame return -- return) compilation
X Drops the frame and move the return values down. The old
X frame pointer and the top of stack at entry of the definition
X are used to restore.
X
X(unlink;) ( frame return -- return) compilation
X Performs the same action as "(unlink)" but also leaves the
X definition. Is compiled by ";".
X
X(unlink>) ( frame return -- return) compilation
X Performs the same action as "(unlink;)" but also performs
X "(does>)". Is compiled by "does>".
X
X(local) ( -- addr) compilation
X Using an inline literal offset within the current argument frame
X returns the address of an argument or local variable.
X
X(local@) ( -- value) compilation
X Using an inline literal offset within the current argument frame
X access the value of an argument or local variable.
X
X(local!) ( value -- ) compilation
X Using an inline literal offset within the current argument frame
X store "value" to an argument or local variable.
X
X-> ( x -- ) compilation
X Assigns an argument or a local variable. Used in the
X following manner:
X <value> -> <frame-variable>
X
Xexit ( -- ) compilation
X Performs the equivalent action of the normal "exit" but also
X restores the stack after argument binding and local variables.
X
X{ ( -- ) immediate compilation
X Starts the named argument and local variable compiler. Used
X in the following way:
X { <argument-names> | <local-names> -- <any> }
X or
X { <argument-names> | <local-names> }
X or
X { <argument-names> -- <any> }
X or
X { <argument-names> }
X or
X { | <local-names> -- <any> }
X or
X { | <local-names> }
X The different parts are optional. The only restriction is
X that the definition is ended by "}" or "--". In the "--" case
X characters until "}" are skipped.

X
XDESCRIPTION
X Allows composition of data field description to build structures.
X
Xstructures ( -- )
X Vocabulary for structure type functions.
X
X+size ( struct -- size) private
X Field for accessing the size of a structure type. This field is
X a long containing the number of bytes to allocate for an instance
X of the structure type.
X
X+initiate ( struct -- initiate) private
X Field for accessing the initialization code of a structure type.
X This field is a ptr containing a pointer to the initialization
X code for the structure type. A zero value, nil, indicates that
X the structure type does not perform initialization.
X
Xas ( -- struct) immediate
X Used as:
X as <struct-type>
X Returns the address of the body of the structure type information.
X
Xthis ( -- ptr)
X Returns the compilation address of the latest defined word.
X
Xinitiate ( ptr struct -- )
X Take a pointer to a memory area and initializes it according to
X the initialization code for the structure type given as the second
X parameter.
X
Xmake ( struct -- ptr)
X Given a pointer to a structure type information block, as generated
X by "as", allocates memory in the dictionary and initializes it.
X
Xnew ( -- ptr) immediate
X Used as:
X new <struct-type>
X Performs the corresponding function as "make" but takes the
X preceding word to be a defined structure type.
X
Xsizeof ( -- size) immediate
X Used as:
X sizeof <struct-type>
X or
X sizeof <prim-type>
X Returns the size, in bytes, of the preceding structure or
X primitive type. The primitive types are defined below.
X
Xassign ( x y -- ) immediate
X Used as:
X x y assign <struct-type>
X or
X x y assign <prim-type>
X Assigns the structure or primitive pointed to by "y" the value
X of "x".
X
Xstruct.type ( -- )
X Used as:
X struct.type <struct-type>
X <struct-layout>
X struct.init ( self -- )
X <inititialization-code>
X struct.does ( self -- )
X <instance-code>
X struct.end
X and then:
X <struct-type> <instance-name>
X Starts the definition of a structure type. The layout
X section <struct.layout> may contain the words;
X n bytes <field-name>
X Allocates "n" bytes,
X byte <field-name>
X a byte,
X word <field-name>
X a word,
X long <field-name>
X a long,
X ptr <field-name>
X a pointer,
X enum <field-name>
X an enumerative, and
X struct <struct-type> <field-name>
X a structure. To align a field to even address us:
X align.
X The initialization code receives a pointer to the block to
X initialize and any additional parameters. Thus additional memory
X may be allocated directly after the block. If the structure
X contains structure fields these should be initialized by the
X initialization code. For this "as" and "initiate" are used:
X <struct-field> as <struct-type> initiate
X The normal action performed by a instance of a structure
X type is to return the address to the instance. The optional
X "struct.does" part redefines the normal action of a created
X structure block. It receives a pointer to the instance as
X parameter and any additional parameters. The parts
X "struct.init" and "struct.does" are optional.
X
Xbytes ( n -- )
X Used as:
X <number> bytes <field-name>
X within a structure type definition. Creates a field access
X name to a <number> of bytes.
X
Xalign ( -- )
X Used within a structure type definition to align the current
X field address to an even address.
X
Xfield ( bytes -- )
X Used as:
X <bytes> field <field-type>
X to create additional field types other than "byte" etc.
X
Xstruct ( -- )
X Used as:
X struct <struct-type> <field-name>
X within a structure type definition. Creates an access field name
X to a structure. The structure is not initialized automatically
X by the structure type. This should be performed by the initial-
X ization code of the structure type it is a part of.
X
Xbyte ( -- )
X Used as:
X byte <field-name>
X within a structure type definitions. Creates an access field name
X to a byte.
X
Xword ( -- )
X Used as:
X word <field-name>
X within a structure type definitions. Creates an access field name
X to a word, two bytes.
X
Xlong ( -- )
X Used as:
X long <field-name>
X within a structure type definitions. Creates an access field name
X to a long, four bytes.
X
Xptr ( -- )
X Used as:
X ptr <field-name>
X within a structure type definitions. Creates an access field name
X to a pointer, four bytes.
X
Xenum ( -- )
X Used as:
X enum <field-name>
X within a structure type definitions. Creates an access field name
X to a enumerate, four bytes.
X
Xstruct.init ( -- )
X Used within a structure type definitions to define the end of the
X structure layout and the beginning of the initialization code. At
X run-time the code receives a pointer to the instance as parameter.
X
Xstruct.does ( -- ) immediate compilation
X Used within a structure type definition to define the end of the
X structure layout or initialization code and the beginning of the
X instance action code. At run-time, performed for the instance,
X the code receives a pointer to the instance as parameter.
X
Xstruct.end ( -- ) immediate
X Used to end a structure type definition.

X.TH TILE 1 "30 November 1989" "Version 2.48"
X.SH NAME
Xtile \- c based forth-83 standard programming environment
X.SH SYNOPSIS
X.B forth
X.RI "[\|" file " .\|.\|.\|]"
X.RB "[\|" \-a
X.IR argument " .\|.\|.\|]"
X.br
X.B forth
X.RI "[\|" file " .\|.\|.\|]"
X.RB "[\|" \-s
X.IR start-symbol "\|]"
X.RI "[\|" argument " .\|.\|.\|]"
X.SH DESCRIPTION
X.I forth
Xuses a command syntax much like a compiler. The
X.I file
Xarguments are loaded before the interaction top loop is started. A
X.I start\-symbol
Xmay also be given as an argument thus allowing
X.I forth
Xto act as a `compile-and-go' compiler of applications. An extra
Xoptions or parameters passed to
X.I forth
Xmay be accessed by the application. As extensions of the Forth-83 Standard
X.I forth
Xsupports multi-tasking, exceptions, vocabulary casting, private definitions,
Xargument binding and local variables. Written in C the kernel may
Xbe used as a general purpose environment for interactive testing of
XC-code.
X.LP
XTo provide an interactive programming environment for developing programs
X.I forth
Xmay be run as a sub-process to GNU Emacs in a specialized
X.I forth\-mode.
XSource code may be edited and directly tested by passing either
Xa paragraph of code or a whole buffer to
X.I forth
Xfrom Emacs. The
X.I forth\-mode
Xalso supports documentation retrieval and automatic indentation of
Xforth code, comments and definitions.
X.LP
XAn environment variable is used to specify file search paths thus
Xliberating and supporting management of libraries of source code.
X.I forth
Xcompiles faster than most compilers link with approx. 50.000 lines per
Xminute on a SUN-3/60, thus code is only saved in source form.
X.SH OPTIONS
X.TP
X.BI \-a " argument .\|.\|."
XAllows access of the rest of the arguments. The first arguments is the string
X.I forth\.
X.TP
X.BI \-s " start-symbol "
XDefines the symbol to be used instead of the normal interaction top loop.
XThe
X.I start\-symbol
Xbecomes the first argument and any further arguments may be accessed by the
Xapplication. The library contains some examples of argument fetching functions.
X.SH LIBRARIES
XThe
X.I tile
Xenvironment has currently three directories with forth-83 source, test and
Xexample code and documentation. The directory
X.I src
Xcontains Forth-83 source code library, consisting of a number of
Xdata modelling, and debugging tools, and high level multi-tasking
Xconstructs such as semaphores, channels and task types. Documentation
Xof the source code and the kernel are found in the directory
X.I doc.
XTest programs for and example of usage of the source library code may be
Xfound in the directory
X.I tst.

X.B TILEPATH
XSearch path for library source files. A normal setting is
X`.:~/tile/src:~/tile/tst' which will allow the file include function in
X.I forth
Xto locate library source files in current directory, the standard library,
Xand the test code library.
X.I forth
Xalso looks for files at the users home directory.
X.SH GNU EMACS FORTH MODE
XThe GNU Emacs forth-mode supports interactive programming, automatic
Xindentation of source code, and documentation search of the
X.I forth
Xkernel and library within Emacs. To allow automatic loading of mode your
X.I .emacs
Xfile should contain the following definitions;
X.LP
X.br
X (set-variable 'load-path
X (append load-path
X '(nil "~/tile")))
X.br
X (setq forth-help-load-path '(nil "~/tile/doc"))
X.br
X (setq auto-mode-alist
X.br
X (append '(("\\.tst$" . forth-mode)
X.br
X ("\\.f83$" . forth-mode))
X.br
X auto-mode-alist))
X.br
X (autoload 'forth-mode "forth")
X.LP
XFurther documentation about the
X.I forth\-mode
Xmay be found by giving the command `M-x describe-mode' in Emacs.
X.SH BUGS
XBugs should be reported to mip@ida.liu.se. Bugs tend actually to be
Xfixed if they can be isolated, so it is in your interest to report them
Xin such a way that they can be easily reproduced according to
Xget newer version.
