COBOL PASSING PARAMETER TO ASM IN REGISTER 0

Postby rbarnach1 » Thu Nov 07, 2013 3:20 pm

Hi,

How do I pass a parameter from COBOL to an assembler program? In the Assembler called program, it is expecting the data in REGISTER 0.

Thanks in advance.

Regards,

Hello,

In the Assembler called program, it is expecting the data in REGISTER 0.
I suspect it is Not the data . . . I suspect it is the address to the parm(s).
Hope this helps,
d.sch.

assuming that you're running in a Z/OS environment...

this seems strange in that the common linkage convention is that the parameter list is passed as a list of addresses in REGISTER 1.

I'm pretty sure that COBOL would always use REGISTER 1.
