Right now, you don't know where the routine converts the binary to text decimal as well as where it stores the text. Because the C128 has a hard wired monitor in its system, I found the decimal text in the stack at $0100. That would be the first place to look in the C64.

In addition, my modest programs are usually intended to replace sluggish sections of magazine type in BASIC programs. Usually, I retain much of the original BASIC code. For this application, I need BASIC ROM. About the only disadvantage to this programming practice is that my programs only work on one COMMODORE computer. If I can at all help it, I program for the C128. Programming for the C64 is like pulling teeth.
