You "only" need to set BASIC start vectors (pages $2B ff., normally $01 $08, i.e. pointing to $0801) in zeropage higher than bitmap, then "below" bitmap would make as much sense than "above" BASIC ROM, i.e. $C000, for your extension. See https://www.c64-wiki.de/wiki/Zeropage

Other (maybe better) idea: switch VIC-Bank to $C000-$FFFF, an area 3 quarters of which aren't accessible for BASIC anyway.

You are right. In regard to continuous basic space the tool is not optimal. The Bitmap already starts at $2000, giving $1cc0 bytes (7360 decimal) for basic code. Thus, I thought it not to be a problem to put the extension somewhere behind $2000, so $4000 seemed just right.

If I put the Bitmap to bank 3 and run the extension from $c000 this would save much more space for basic code.

I will think about this, maybe in combination with a real usr function, I.e. Native basic command with parameter parsing from basic command prompt.

Since it's a BASIC extension, would not $c000 be a better location for the routine?

Draw lines and plot dots using V2 BASIC with just 611 bytes. No Simon's Basic or other extension needed.
