The EXFMT operation is a combination of a WRITE followed by a READ to the same record format. EXFMT is valid only for a WORKSTN file defined as a full procedural (F in position 16 of the file description specifications) combined file (C in position 15 of the file description specifications) that is externally described (E in position 19. of the file description specifications)
Factor 2 must contain the name of the record format to be written and then read. A resulting indicator can be specified in positions 56 and 57 to be set on if the EXFMT operation is not completed successfully. When the indicator is set on, the read portion of the operation is not processed (record identifying indicators and fields are not modified). Positions 54, 55, 58, and 59 must be blank.
For the use of EXFMT with multiple device files, see the descriptions of the READ (by format name) and WRITE operations.
