I have created a nice little language file for BASIC7800 for Notepad++.
If you have never added a language file to Notepad++ use Language>user defined>define your language>import. It's set for .b78 files to pull in the language file.
and for you don't know what a language file is it tailors Notepad++ to the specific programming language or dialect highlighting different kinds of commands in different color and generally making the file easier to create and read.
