No line numbers but you can use numbers as goto labels. It uses Dynamic Dialog Tools which is a Win32 wrapper which most of my "job" is gutting out those calls, implementing Single Responsibility in functions and plugging in Electron UI. And trying not to break EVERYTHING...

Thanks for clarifying. Super smart approach to adopting legacy code to a modern interface.

Maybe I missed it, but are you still using the Powerbasic compiler or have you worked around that somehow?
