780 is trying to call the trap - so it depends what values you are entering

You line 780 call the trap with the values in the address and data registers. I followed the examples in the book and what should work doesn't

Function HEXDEC is not returning proper result - you have an error in line 1070
Change it to : 1070 IF v>47 THEN v=v-48
Corrected program in attachment - now also runs when Toolkit 2 is loaded

Thank you Andrew! I fixed the HEX$ by Changing to HHEX$, I dont know how i missed the IF V>47 line since I looked at that function for hours!

It was probably BECAUSE you looked at the function for hours and always read what you thought it should be. Been there, done that.
