I think I have asked the wrong question. On Windows I have something similar to mingw - ie I make use of msvcrt.dll - and I only use C90 functions. The equivalent of that on z/OS is to use LE, not do SVCs. So my question is - is LE documented (msvcrt isn't), or at least well-understood, such that I can clone it in z/PDOS? LE is well over 20 years old, so patents aren't an issue - if they ever were. Copyright isn't an issue - I will be writing my own version of anything. I don't have access to IBM's source code anyway. My main interest at this point is z/PDOS and z/OS, but I do have an interest in MVS 3.8J too - so - if I did have a mini-clone of LE, would I be able to run it on MVS 3.8J if I put my clone into the linklist, or is that not how LE works? And indeed - even on z/OS - do I have the ability to STEPLIB to my own LE clone to override the z/OS version if I wish? Thanks.
