VERY COOL!

Thanks Cetin! The only thing is that it stops after it is changed and when I choose debug, I am in the code in the next procedure AFTER the change, not where it actually changes...hmmmmmmmmm

SET ASSERTS ON
ASSERT UPPER(LEFT(map_type(1),3))!="NON" ;
    MESSAGE "map_type(1) has just changed to "+map_type(1)

>Ok, please someone who is thinking more clearly than I this morning refresh my memory on how I can trap for when the value in a variable map_type(1) changes in a program? My variable's value is changing unexpectably and I need to determine when it occurs in the app. Can this be done using the debugger in VFP8?
