Subject: How CP/M programs were patched

> My recollection is that most CP/M programs were configured via patching. At least that's how I configured them. I remember my WordStar manual coming with details about which bytes to patch to do what. There was also a few dozen bytes of patch space set aside for you to write your own subroutines, in case you needed to add custom support for your printer.
