Not to mention a cpu hog.
That's why we suggest doing those compiles with our C/C++ compiler
running in IBM compatibility mode on a local workstation... saves
a lot of memory & CPU.. and, if you are being billed for those,
it can save a ton of $$$.

Dave,
Do you have any documentation on how to do this? Do you require the IBM C *.h
files on the PC? Is the output usable for a UNIX command environment (your
output is/is not LE?), CICS transaction, CGI?

Hi John,
Our compilers operate in several "modes" - one of which is
"IBM Compatibiltiy mode".
When "IBM Compatibiltiy mode" is enabled, you need the IBM
headers to compile with (you can do that with a SAMBA server
on your mainframe; or an NFS server on your mainframe.) The
resulting object is "just like" the IBM compiler had compiled
it. Of course, since it's not the same compiler, the code
is not identical - but it is LE, just as if the IBM compiler
had compiled it.
The resulting objects would then be linked with the IBM
LE runtime for execution. Our pre-linker can also stand-in
for the IBM pre-linker, if you wanted to use that instead
of the binder. And, our linker can do binding as well,
creating a TSO transmit file that is RECEIVED on the mainframe
(although, it will only create old-style LOAD MODULES, not
the newer PROGRAM OBJECTS.)
The output is usable in all the same ways as the IBM compiler's
output is usable.
As well as compilers, we also have a CICS preprocessor and DB2
preprocessor - so all of that can happen on your PC as well.
More information can be found in our Systems/C documentation
(http://www.dignus.com/dcc/doc.html) and our Utilities
documentation on that same link.
