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

Retrieves the next record from a file. If the record is 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.
The reference of the record is written to the target noun REFERENCE.
