FIELDS

The control field begins on the first byte of each record in the input data set, is 2 bytes long, contains character data, and is to be sorted in ascending order.

CKPT

DFSORT takes checkpoints during this run.

Note: CKPT is ignored if the Blockset technique is used. If checkpoints are required, you must bypass the Blockset technique by specifying the NOBLKSET option, or by specifying installation option IGNCKPT=NO. However, functions such as OUTFIL, which are supported only by the Blockset technique, cannot be used if the Checkpoint/Restart facility is used.

EQUALS

The sequence of records that collate identically is preserved from input to output.

NOCHALT

Only AQ fields are translated through the ALTSEQ translate table. If installation option CHALT=YES was specified, then NOCHALT temporarily overrides it.

NOVERIFY

No sequence check is performed on the final output records.

CHECK

The record count is checked at the end of program processing.
