Hi Tracy,

I am guessing the array gets passed by reference a lot and therefore just setting set a breakpoint on a map_type[1] won't work.

If that's the case, build an expression like
!Type("map_type[1]")=="U" and map_type[1]==[YourCopiedValue],
set a breakpoint and it should fire after the call in which
the arrayelement was changed (if the array is named differently
in the called method/function).

Repeat recursively as needed <g>.

HTH
