This should address the backspace issue.
Things to note. I had to add this line to the NUMBER2: sub-routine:
_PRINTSTRING (55, 30), SPACE$(40)
It is absolutely needed to clear the field before the number is printed when backspacing, but also when any result has fewer digits than the previous shown result. Now you may want to use something other than SPACE$(40) that will clear the field.
Next, I also had to make a different way to handle not accepting more than one leading zero in a non-decimal entry.
IMPORTANT: You need to revisit the CLIPBOARD routine. I could easily paste a sequence of like 0000...0.0 and it would be accepted. It would also screw up any attempted calculation.
Anyway, there will probaly be other athings to consider with the other math functions. I'm only checking +-*/.

END SUB 'Clear_MBThings to note. I had to add this line to the NUMBER2: sub-routine:
_PRINTSTRING (55, 30), SPACE$(40)
It is absolutely needed to clear the field before the number is printed when backspacing, but also when any result has fewer digits than the previous shown result. Now you may want to use something other than SPACE$(40) that will clear the field.
Next, I also had to make a different way to handle not accepting more than one leading zero in a non-decimal entry.
IMPORTANT: You need to revisit the CLIPBOARD routine. I could easily paste a sequence of like 0000...0.0 and it would be accepted. It would also screw up any attempted calculation.
Anyway, there will probaly be other athings to consider with the other math functions. I'm only checking +-*/.
