Hello, again.
Same situation as before, sorry.
Can anyone enlighten me as to why:
msg_len EQU (message_end - message_start)
message_start:
retlw b'00000000'
[... etc ...]
retlw b'11111111'
message_end:
Gives me a:
/usr/home/willmore/src/pic/test/10/test.asm:35:Error [116] Value of symbol "message_len" differs on second pass
pass 1=0, pass 2=125
Error code : 256
It seems that it's upset that when it first evaluates the
expression, it has no values for message_end and message_start,
so their difference is 0, but after having a longer look at
things, it decides that it's now 125. This causes a bit of
confusion and an error.
Again, am I missing some common trick or am I expecting
the wrong things out of my tools? i.e. pilot error or
pilot error. :)
Cheers,
David
