Document your source
Documenting your source is now easier than ever. Editor/400 has several functions build in that makes documenting your source fast and simple. Press F7 with the cursor on a file, field or program name to put the description of the subject in the commentfield of the sourceline. Use F19 (Shift F7) to put that description in a commentline above the subject.
Use a 'P' in the commandfield of a sourceline to add a complete source header, containing program name, description, user name and description and date to your source. With the '*' and '-' command you can simply add a line with *'s or -'s to your source.
