Guitscal.zip contains two fret scale calculators for guitar builders. Both Scales.bas and fretscls.bas require GW Basic to run Both programs are public domain software. They are not fancy by any means. And useful only to a specific few. However for those few, they make a real pain in the ass job much easier. To invoke type: > Gwbasic scales.bas or >Gwbasic fretscls.bas Then press Enter or Return. For those not used to Basic programs I will remind them that when wishing to leave the program, type system, when the screem says OK.
