Update long control

The process option UPDLDEL produces an update file that contains control records, matching new file source records, inserted new file source records, and deleted old file source records.

The UPDLDEL process option is available for the LINE compare type only.

Figure 1 shows an example of a UPDLDEL update file.

The control records are titled as follows:

*HDR1, *HDR2, *HDR3: Header titles and data
*M-: Matched line sequence header
*I-: Inserted line sequence header
*I-RP: Inserted line sequence header for replacement lines
*I-RF: Inserted line sequence header for reformatted lines
*D-: Deleted line sequence header
*D-RP: Deleted line sequence header for replacement lines
*D-RF: Deleted line sequence header for reformatted lines

Header control records are full length records that delimit the copied file records. This allows you to quickly find changed areas. The records look like the information about a LONG listing. The two input files must both have the same fixed record length or each have a variable record length.
