• &FILE GET

  Retrieves a record

• &FILE PUT

  Adds or updates a record

• &FILE DEL

  Deletes a current record

• &FILE CLOSE

The following system variables are provided to help test the success of functions:

• &FILERC

  the completion code for the last function

• &FILERCNT

  the number of records processed by the last generic delete (&FILE DEL) operation

• &VSAMFDBK

  the VSAM RPL feedback code from the last function

• &FILEKEY

  the key of the last record referenced
