Hi John,
Systems/C can run on your AIX/Win32 environment and generate mainframe
programs (i.e. it can cross-compile); with that you can use your
existing build environment to build the mainframe program. In fact,
with Systems/C, you can actually link on your AIX/Win32 platform
generating a TSO TRANSMIT file that can unloaded on your mainframe.
You don't need to worry about the digraphs/trigraphs, all of the
mainframe compilers will support brackets, etc...
As far as generating something that is callable from ASM and COBOL,
the Systems/C "Direct CALL" (DCALL) environment is perfect for that.
You could generate a function that is directly callable from both
of those.
For more information about Direct-CALL, see the Direct-CALL chapter
in the Systems/C Library Reference (http://www.dignus.com/dcc/clib.pdf)
If you have any questions, feel free to contact us!

Hey all,
I have recently inhereted an application that was written in C on a Win32 /
AIX platform that needs to be moved up to the mainframe (z/OS V1R4.0).
I have never had to use the C compiler on the MF and to say I am confused
would be an understatment. I know I am missing some connecting dots.
In order to compile the routine we have had to replace all our square brackets
with trigraphs and digraphs. I know there has to be a compile option that
pretty much emululates a win32 or AIX environment as far as acceptable chars.
Also, this routine is going to be used as a called subroutine by both
Assembler and COBOL. In the Win32 envirionnment, I don't need a 'main'
section and I can compile it into a .dll thereby making it unique and
callable. However, on the MF I can't get past the compile without a 'main'.
And linking is another problem... sigh...
I'm looking for a boost up here. Is there someone on the list who would be
willing to help me work through some of the issues I'm having?
Many Many thanks in advance.
