Smyte,
I seem to remember something similar and if I recall correctly it happend after I upgraded to a new version of a particular WestWind class. I think VFP has problems with #define the same variable name multiple times.

Example:
#define myVar = 5
#include myfile.prg

myfile.prg
#define myVar = 5

Did you recently add any new #define?, if you did make sure the name is unique.

Hope this helps.

>Hello all,

I haven't made any changes to the file nor have I intentionally changed anything which would cause this. So, can anyone tell what I might have done? Something global that I'm not aware of? I'm also using a west wind class and the same thing happens to it now.
