2022-08-19 09:57:45 <KipIngram   > vms14: Whem I started my system, I first wrote assembly to just "exit" (there's a syscall for that).  Then I made that a primitive and wrote the little vm and ran a definition that called the exit word.  Etc. - built my way up.  Generally if I caught a bug it would segfault - if it didn't, it was likely working.

2022-08-19 09:59:27 <KipIngram   > If some significant definition has a bug, you can move an  "exit" word through it, starting from the beginning - first time it segfaults, you just moved that exit over the troublemaker.  You can drill down into a definition hierarchy that way to find your problem.

2022-08-19 11:50:31 <KipIngram   > Oh sure - it was the simplest equivalent to a "debug print" I could think of.  Just "can I quit cleanly?"
