Turbo Pascal used to support building your program as multiple executables with a shared data space, so you could chain from one part of your application to another.
Turbo Pascal also supports overlays, which allows you to chunk up your code and swap it into memory. I genuinely enjoy using the Turbo Pascal IDE on either my 1984 Kaypro or the monster 16-core “Zedripper” Z80 laptop I built. It’s great!
I really liked your Zedripper page!
Thanks - I'm looking forward to going back to commuting someday, so I can actually use it!
