I recently posted a question about passing things like "==" to macros;
this is in the context of trying to get Brad Minch's 18F2455 usb code to
work under gpasm. I didn't get a real solution to that, but did find a
work-around that is satisafactory for my needs. I do think there is a
significant difference on that score between mpasm and gpasm macro
processing, though.
Now I have a new issue: It seems to me that there is no way to have more
than one #v(expression) occurence in a single macro line. For
instance, if you wanted a line within a macro like:
goto label#v(row)_#v(column)
(where there are labels defined somewhere else such as label1_1,
label1_2, label2_1, label2_2)
This will generate syntax errors, as far as I've been able to tell.
I've tried to work around this but have not figured out a fix. So I
started to look into the gpasm source code, which I am not particularly
qualified to do!
Does anyone have a clever suggestion for a workaround, or do the
developers have any pointers about how I might, for example, tweak
scan.l to do this? (I was thinking a brute force approach might be to
add a #w(expression) "operator", but that's not very good.)
