Commander X16

I would love to see the Basic language in ROM somehow get a renumber command similar to the command of the same name in the Commodore 128/plus4. Coding long complex Basic programs is a lot easier (using the interactive coding style basic allows) to write if the lines can be renumbered on the fly. Also, I have tried a RENUM utility found else where on this forum, but it doesn't seem to work on v42.

This was a recent post that I was directed to, when I inquired about an auto-numbering feature in the CX16's BASIC ROM. Don't know if it would work for your case or not..

There will be REN (for RENUMBER) in the next release.

"Syntax is REN [<new starting line number>, [<increment>, [<first old line number>]]]

Please SAVE before trying to renumber a program, and consider this feature experimental."
