Question about string handling.

[matchy]

I think the right$ thing might evaluate a tad faster, though.

How about the speed of MID$ command?

[Kitty Hello]

left$, right$, mid$ are basically the same command. The replace might be a tad slower when the string lengths of needle$ and haystack$ are not equal.

The problem with most of your function is/was that numbers converted to strings used to have a space in front (the hidden + (positive) sign) so you used to do:

A$=right$(str$(n),Len(str$(n))-1) just to remove this blank, on the c64 and others.

Well, the C64 didn't do automatic type conversion in BASIC
