The learning curve for Hercules can be pretty steep, as it drops you in to a working version of MVS 3.8j. If you are familiar with all that means, you are golden. The rest of us need some guides. Moshix has a great YouTube channel with lots of good videos. I started with his "IBM’s MVS 3.8 on Linux for newcomers - M50"[0], and I had a sample ancient COBOL program, with assembly language subprograms, running in under an hour. My main issue was the editor or shell (not sure which) locking up and not able to get out. I can kill the Linux process, but that leaves all the mounted disks in a slightly corrupted state, and doing the equivalent of fsck is beyond my skill level. I just reinstalled the Hercules package again, with a pristine set of disks, but that isn't going to help if I had a real program I was working on. Maybe there is a recovery guide for common hangups that I haven't discovered yet.

Hercules does not come with MVS 3.8j, that just happens to be the version of MVS that is available publicly. You can also run several other mainframe operating systems on it. > My main issue was the editor or shell (not sure which) locking up and not able to get out. More likely, the terminal locked up. If you try to type where there is no field to type into, you'll lock the keyboard. To reset it, press Escape, then tab to the field you want to type in.
