Hello Dave, Thank you for the suggestion. I found that we are not licensed for c/c++ compiler for z/VM. I will try to follow your suggestion of compiling on z/OS and then binding on z/VM.

Hello, Ashwin. I would suggest that you first attempt a straight port of your C application over to z/VM.....it supports the same C/C++ compiler that is available on z/OS, and the z/VM LE level is at (if I remember correctly) the z/OS 1.9 level. In fact, if you do not have the z/VM C/C++ compiler installed, you might try simply compiling the code on z/OS, and then move the object text file(s) over to z/VM and bind it there with z/VM's LE libraries. z/VM now supports the z/OS binder as well. The LE socket library calls (BPX1xxx) should work on z/VM as they do on z/OS. Let us know if you run into any problems......I think you'll find the CMS environment a pleasant one to do code development in.
