#IF statement in macro problem

[Jacques Nilo]

Hi all
I am wondering why the following test program returns 5 and not 6...
Any suggestion/workaround are welcome !

end macro

cls
PPSMapIn("RB5",RXPPS)
print RXPPS

This is because of the process order of GCB- ifdefs are processed first then are resolved then processing continues. (I stand to be totally correctly by Hugh). :-)

I would change to a sub with parameters - macros will also create more inline code, again recommend using subs unless speed is your real issue. change the ifdef to if then.

I was trying the macro route because I was trying to generate a variable name dynamically and then assign a value to it according to the pin input.
I am thinking about the most efficient way to create a pps library that is missing today.
PPSMapIn(pin,fn) would assign function fn (CCP1,CCP2,RX,...) to the pin given as parameter (RA0,RA1,...)
Likewise for PPSMapOut
