Hi,
I want to program a serial number with the melabs programmer and use it in my program.
Therefore, I added following code in my program;

adrs VAR BYTE
ReadCode $0FFF, adrs '

And this is what I get during compiling:

*** 7 Errors ***

How does this come, and what can I do to make it work? Without the 2 lines of code I don't have any error.
