I am considering doing the interface in Assembler. Which PL/I compiler are you using? If you are using Enterprise PL/I then you should simply be able to declare your C functions and subroutines in PL/I with the appropriate parameter attributes. All of C's attributes are available in PL/I and have been for over 20 years. If you post a couple of C prototypes here, I shall translate them into PL/I for you and you can use them as examples. Post the most complicated one(s), typically those with the greatest variety of parameter types. If you are still using the old OS PL/I Optimizer, good luck -- you'll need it. -- Regards, Dave [RLU #314465] *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* david.w.n...@googlemail.com (David W Noon) *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
