Had an interesting Flashback as looking at use of #Macros in #Rocket_rs in #RustLang
One of my favourite historical programming achievements was a highly optimised ListBox in #DataFlex 2 written as a "Macro" (new command). Each extra instance reused the vast majority of code because we got close to limits.
This was for MsDos systems with 80 characters x 25 lines.
This was with the United Bible Societies in (I think) late 80's early 90's.
