I noticed on my postings that some had commented that the
ICONX PROGRAM ...
is unnecessary. This may be partly true under unix. MSDOS needs the ICONX
all the time. Under VMS we have a script called IEXE which converts
ICONX PROG unto a symbol(alias) PROG. This is handy for utilities that
are used very commonly. Under VMS icon paints screens so slow that I
usually use DCL (shell commands) to build the screen or menu, and build icon
filters to manipulate the files underneathe.
Some years ago I ported ICON to a ZS-1 super-minicomputer from Astronautics.
There were certain configuration parameters that were set before building
the software. One or more parameters were concerned with whether icon utilities
needed iconx explicitly, or if it rolled a little executable into the icode.
However, since main(){printf("hello\n");} generated about 200k of executable.
The icode of most of the utilities I wrote was typically 2-4k, and the disks
were pretty full, it was smarter there to keep the icode separate, so iconx
would be required. That was in the Icon 7.0 days, and maybe Icon 8 is much
different under unix.

What I wrote was that the `ICONX' is system-specific, and that the users of systems which do not have direct execution (VMS, ms-dos) will know to use it. Because commands are case-sensitive, `ICONX PROGRAM' won't work on most unix systems. > The icode of most of the utilities I wrote was typically 2-4k, and the disks > were pretty full, it was smarter there to keep the icode separate, so iconx > would be required. It would be interesting to compare the size of the compiled code on various systems. The canonical hello.icn compiles to 6941 bytes here (Xenix 386, direct execution). Is it much smaller on VMS or ms-dos systems without direct execution? -- Ronald Florence ron@mlfarm.com
