The weird thing is that I pressed the Save button (containing the TABLEUPDATE function) a few times in a row before I got the error message, but pressed the Edit button in between. So it is apparently working sometimes.

IF you have tables in your DE, just set the cursor's buffering property to the correct setting. If you are opening your tables manually, set buffering with CURSORSETPROP().

Also, you should probably make a habit of including the alias parameter in your TABLEUPDATE and TABLEREVERT commands to ensure that you are updating and reverting the table that you think you are.

TABLEUPDATE(.T.,.T.,"MyCursor")

TABLEREVERT(.T.,"MyCursor")
