I wrote a BASIC routine to open files in notepad++ from TCL.
It follows the structure of NPP {FILE} {RECORD}.
This came from the idea of when I wrote the e shortcut to open explorer.exe from the windows subsystem for linux. Very useful to be able to launch gui applications from anywhere and with wintegrate scripting its possible from UniVerse.

I also wrote a version for VSCode but it's a little bit more janky and slow so I'm not a fan of it.
