I am learning how to use the linker on MPLAB 6.10. So far so good, but something I realy don't like is the way you have declair addresses and registers with GLOBAL and EXTERN, etc. Isn't there a better way of doing it? Seems like a lot of extra work and when I am going to do a large program I think it is realy going to irritate me. The help file refers to a .MAP file, where you can see your memory usage, etc. I can't find any. Do I have to be set in on a command line? If so where?
