One thing I want to get in some of the BASIC editor extensions (like the cool CoCoTools for Visual Studio Code) is the ability to force code to stay where it is (subroutines) while RENUMbering everything else.

5000 REM INPUT
5010 LINE INPUT A$:RETURN

5500 REM OUTPUT
5510 PRINT A$:RETURN

There are ALOT of problems trying to do this, but just having it leave lines alone that are marked somehow, so a RENUM would do anything except lines marked. I thought maybe using “:” would work, since you cannot use that on a REM line and do anything:

5000 REM:INPUT
…
5500 REM:OUTPUT

Then as it renumbers, it would leave those lines alone, and reset whatever the “current” number is so renumbering starts there as if I did it manually with multiple renums.

Does that make sense?

To do it manually:

1 PRINT “ENTER YOUR NAME:”;
2 GOSUB 5000
3 PRINT “HELLO, “;
4 GOSUB 5500
5 END
5000 REM:INPUT
5001 LINE INPUT A$:RETURN
5500 REM:OUTPUT
5501 PRINT A$:RETURN

Then you’d RENUM but you’d get:

10 PRINT “ENTER YOUR NAME:”;
20 GOSUB 5000
30 PRINT “HELLO, “;
40 GOSUB 5500
50 END
5000 REM:INPUT
5010 LINE INPUT A$:RETURN
5500 REM:OUTPUT
5510 PRINT A$:RETURN

But I am sure there would be many unforeseen issues.
