Question – are any of the fields you are updating part of the key?

And it’s one update per acquisition of the record
The chain, read, reade, readp, readpe lock the record
The update unlocks the record
So if your code goes:

Chain

CheckFld1
Update

CheckFld2
Update

The second update would fail whenever the record was updated and unlocked in the first instance.

Hi,

Before updating a record you will need to read or chain that record to position the file pointer in the program to the correct record in your file. You can use READ, READE, READP, REDPE/READPE, or CHAIN.
