Incorrect Line numbers (*solved*)

[boriel]

I'm getting an error in the code "illegal character _ at line xxx"

And there isn't one in line xxx.

I suspect that this line number comes from the assembler, and it's a line number based on the code stripped of comments and white space perhaps?

I've noticed that it's sometimes hard to pin down the correct line number for errors before.

Than paste the piece of code which produces the error, so I can try to reproduce it here.
