>> Is it possible to statically call a C routine from a COBOL pgm?
Nothing more simple than that...

Yes, but not through the RETURN-CODE special register.
>> Do i need to use #pragma for this?
I use #pragma linkage (NSBCGDRV,COBOL) where NSBCGDRV is the name of the
function as well as of the load module. That tends to make things easy.
>> Can i return a string from the C routine to my COBOl pgm?
No sweat. But do pay attention to the fact that your average C string will
be null-terminated, where the common COBOL practice is to have fixed-
length, blank-padded fields to hold character data. A conversion routine is
easily written, either in C or in COBOL (UNSTRING is a COBOL statement, the
power of which is very underestimated...)

The prototype of my C function is:
void NSBCGDRV(void *PARM, void *rc);
The COBOL call looks like this:
01 W00-NATSTAR-PARM.
05 PARM-RET-CODE PIC S9(4) COMP.
05 PARM-VALUE PIC X(255).
CALL 'NSBCGDRV' USING PARM-VALUE PARM-RET-CODE
