[open-cobol-list] Re :static cob 2 c: Knowing the number of params?

[Roger While]

Firstly, grab the CVS snapshot tarball (AKA prerelease) at
http://www.sim-basis.de/open-cobol-0.33.tar.gz

(That's if you have not already done so)
This has an enormous amount of changes over 0.32

Sure you can get access to the number of call params.
In your C code do a
#include <libcob.h>

The number of call params is then available in a
field called "cob_call_params" (Auto imported from libcob).

As an extension, OC also has an internal field named
NUMBER-OF-CALL-PARAMETERS for use in Cobol progs.

You can not get the field type as the normal call-by-reference only
passes a pointer to the data area. (This is also what MF does)
