Locking occurs on the READ not the UPDATE opcode.
So when you do the READ, the record is locked until:

It is unlocked with the UNLOCK opcode.
It is written back to the database with UPDATE.
The program closes the file.

You can avoid locking the record in the first place by using the "N"
operation extender:
  READ(N) MYFILE
 or
  CHAIN(N) MYREC
Reads the record and avoids placing the record lock on the record.

Mike,

That doesn't help him.

He wants to be able to unlock the record from the program locking it.

WAITRCD affects how long some other program will wait for a locked record.
It has no effect on the program locking the record.
