> trying to write assembly for insertion into an existing program Ah, all that was old becomes new again. One of my projects in university (35 years ago) was to write a pop-up 6502/8080 assembler for DOS. It hooked into the bios keyboard ISR, in a similar way to Sidekick (anyone remember that) and would assemble any code typed into the window on the fly. The use case was to insert inline assembly code into high level languages without having to leave the IDE/editor.
