I converted a report to VFP and changed an expression on one of the fields because I'm not using the old udf()

Building the .app generates an error in the report because there are entries in the .frx (table) from the old DOS platform. These entries call the old udf which no longer exists.

I need to delete these entries, but doing so with a simple DELETE ALL FOR PLATFORM="DOS" causes a GPF when I try to modify the report.

How to get rid of these entries so my app will compile cleanly???

TIA
