I think I'd start simple in order to find out where the failure is occuring:

a) try exclusive on table
use enroll exclu
*-- make sure .t. is returned.
llOk = cursorsetprop('buffering', 5, 'enroll')
edit a single record.
x = tableupdate(1, .t., 'enroll')
?Did it work?

b) try adding a record.
check the primary key - no duplicates?
attempt tableupdate on a single insert.

In other words - start very simple - working your way up until you remove the exclu, progress onto more than one insert, check and assume nothing. Its vfp you know.

everytime. I've tried recompiling the form, rebuilding the index, rebooted...everything I can think of. Somehow, I think I'm missing something really basic. This is a VFP 5.0 application that I've inherited. Here's the code
