Thanks Bill. This corresponds with Michael's suggestion #2 above. I'll
try this method and see if it is fast enough for what I am doing. I'm
working my way through an old book with a mixture of 6502 and
Applesoft. I didn't like the way the book was doing hex to decimal
conversions, which is why I wanted to use INSTR. I remember that on
more fully featured MS BASICs, INSTR was very fast.

Speaking of missing BASIC keywords, I see that MOD is also missing
from Applesoft. Another very useful function.


A fairly fast hex-to-number conversion routine is in lines 210-260 of:

...as I said, I try not to need INSTR.  ;-)
