What are oApp.Occurs() and oApp.At() ? Are you sure it is the UCase() rather than these which is causing the problem?
IAC, it would be more efficient to create upper case versions of the string for use in those functions rather than repeating the conversion each time.
Does using ToUpper() rather than the VisualBasic namespace UCase() also cause the OOM ?
