Yeah, true...topic drift. Renamed. >So what's really going on here that is the mystery? >My guess is: you have a C function that you want to >call from, in this instance, a PL/I program. Right?

The previous post had an example from COBOL; C is the same, only in C syntax. Assembler too. We validate that we got three or five arguments (note there's an initial, required argument). >Finally: there are some differences in the Enterprise >PL/I compiler regarding compile time options and >options available for declaring functions and >subroutines so I ask this: is your expectation that >your customers will be running the Enterprise PL/I >compiler or some earlier compiler?
