I am having a intermittent problem where the data of some records in a cursor are being replaced with chr(0).

I have an application that creates and indexes some small Visual Foxpro cursors from SQL (using SQL EXEC) and after some intensive Foxpro processing some of the records have chr(0) in all their fields instead of data. The weird bit is that underscores are not replaced with chr(0).

I've seen this type of thing before in data when the table or cursor has a corrupt index. I don't think this is the case this time, but could this be due to memory problems?

The setup I am using is VFP6 SP5 / SQL 2K SP2 running on W2K server SP2.

Any help would be gratefully appreciated,
