Notes:
The record length may be any decimal or hexadecimal number in the range from one through

The receive punch record length specified should take into consideration:
• Output device capabilities of the local station.
• Transmission record lengths of the remote station.
The RPURL specified should be equal to or greater than the recorrl lengths being sent to avoid
truncation. For transmission/ reception of fixed length records, both terminals should agree on
the record length. Records received that are longer than the specified length will be truncated to
the specified length. The number of records truncated during the reception is displayed as pan
of the reception compkte message.
