Re: Parameters changing to NULL

[Ron Norman <rjn@xxxxxxxxxxxx>]

Yes that is the issue. 

There is a C to COBOL API that let’s you specify how many parameters are being passed.

We think we know what is going on.

We have COBOL calling C calling COBOL.

COBOL calls C with 1 parameter.

C calls COBOL with 2 parameters.

There is code in the cobol runtime system that is checking the number of parameters it was called with and NULLING out any "Extra" parameters.

But the code assumes that the number of parameters passed from COBOL To C (1) is still in effect when C calls COBOL.

does this make sense?

What is the best way to code around this?

cobc -C *.cbl

-C translation only; convert COBOL to C
