Fellow ORCA/C buffs...
Does any of you know whether initialization files can be made from ORCA/C?
Also, do Init files have to be non-interactive?
Are there any books with any detail of the subject?
(Don't you dare say Toolbox or GS/OS reference, I already have those)

They most certainly can. >Also, do Init files have to be non-interactive? Doubt it. >Are there any books with any detail of the subject? Not really. But the documentation that does exist makes it clear that Inits are loaded/executed/disposed of in exactly the same way except for one: inits end with an RTL and not a Quit call. trivial example: #include <stdio.h> void main (void) { printf("Hello, World.\n"); getchar(); } #compile hello.cc #rm hello.root #link hello (I assume your KEEPNAME and LINKNAME are $) #filetype hello $b7 (temp init) What happened? We killed the code that Orca adds onto every C program that parses the shell command line into argc/argv variables, before creating the final program. The problem is that when you have more subroutines and source files, you have to remember this simple rule: If the first filename given to the linker has no .ROOT file, then the first function in that object file will be the one called by the O/S and not main(). Try some experiments and see what works. I suspect that parts of the stdio library are dependent on the Orca shell being available. When I get some time I am going to work on replacements that are purely GS/OS and tool dependent so Orca's weak library will not be a problem. Todd Whitesel toddpw @ tybalt.caltech.edu

I think there were bugs in the run-time start-up support in ORCA/C 1.1, but a corrected SYSLIB is available for downloading on AOL.

Most INIT's just quietly do their thing while GS/OS boots without letting
the user know, but it IS possible to gather input. Witness the INITMaster TIF
by Bill Tudor. It starts up a bunch of tools, pops up a desktop (complete
with a blank menu bar) and a dialog box with two scrolling lists. It lets you
modify the "Active" bit of INIT's and desk accessories before they actually
get loaded into the system.
