You probably have a build up of spill locations. Look in the .map file for your project for any variables with 'sloc' in the name.
You will get spill locations any time you have too many active variables in a routine. In my experience, the best way to deal with them is to make simpler subroutines. Strictly scoping all your variables seems to help make more of the spill locations overlayable, which helps as well. You can also move some values into globals, which helps a little--but this way leads to danger from too many globals. If you are working with pointers a bunch, it helps to specify what type of memory a pointer is pointing to, instead of using generic pointers. If you are doing a lot of manipulation of long ints or other 3 or 4 byte types, and you can't reduce your variable usage, your last hope is to port the routine to assembly. Fortunately, there is no need to remove all the spill locations, you just need to keep the number small enough that your code builds and runs. --Mark Swayne Jesse Lackey wrote: > Hi - I'm using the large data model, and as I understand it all globals > are in external RAM.
