In my time at an IBM shop, I remember that one had to keep track of your files
manually, that is, there was no directory structure. You had to indicate the
starting cylinder and tracks for each file. This was especially true scratch
areas for sorting. I can't tell you how many times someone (not me) would
overwrite a file because their sort routine used a scratch area on disc that
overlapped a production file. Yikes.

Here's a little tutorial. It's interesting to see what came through to MPE.
