shared variable slots

One comment that Sven made about using registers as variables. In Keil, you can equate variable names with registers so that you can, within a local program segment, have meaningful names for variables stored in registers.

testvar  equ  R5
testvar2 equ  R6

tp1:
    mov  A,testvar
    mov  B,testvar2
    add  A,B

    ret

Hi Tom!

That's an excellent idea. Have never seen that before and actually never thought about it, since when I write the programm, I know the purpose I use the registers for anyway and I usually comment my programms a lot.

Your method is much better.

Take care
Sven
