visual cobol program - calling a PCO program - animation shows it calls the PCO, and then continues on - but the PCO seems to be doing NOTHING, even tho we put a display as the first line to execute in the the pro cobol pgm ....  where to start looking at what is wrong

Hi Al,

Is any runtime error returned, eg. RTS 173 progam not found?

Can you confirm, is this a Visual COBOL question, would it be best placed to post on the related forum, see here:https://community.rocketsoftware.com/rocket-visual-cobol-28
Please let me know if would like this post to be moved.
 

Regards,
Kim

@Al Fedeli 

When you said a PCO program are you referring to Pro*COBOL ? Is that program compiled to a DLL and are you using a COBOL CALL statement to call it from your Visual COBOL program? Have you tried compiling it with ANIM and stepping into it from the debugger?
