EXTERNAL GET NOWAIT LOCK THIS XGNLT Standard Verb External File Access Operation
Target = REFERENCE (RF), EXTERNAL ECHO (XE), FILE STATUS (FST)

Retrieves the present record from a file and locks the record. If the record
is already locked by another user, it immediately returns with a message of
"conflict" in EXTERNAL ECHO and a status of 3 in FILE STATUS.
This is particularly useful after having positioned the file pointer directly
ahead of a record with the verb EXTERNAL BEGIN THIS, enabling you to retrieve
the previous record in a file.

EXTERNAL GET NOWAIT LOCK THIS in file FILE

FILE is the name of the file whose current record is to be accessed and
locked.
