INPUT control statement

Specifies the input source of the HD unloaded data set and specifies whether IMS HP Load invokes a user exit routine.

This control statement is optional. If you do not specify this control statement, INPUT=DFSUINPT is used.

IMS HP Load can reload an unloaded data set that is specified in the DFSUINPT DD statement in one of the following formats—created by IMS HP Unload—or in an equivalent format created by a compatible program:

  • The HD format
  • The HD format with compressed segments
  • The short header format
  • The communication industry standard format (see Restrictions)
  • The communication industry partitioned format (see Restrictions)
Restrictions:
  • If the database has a logical relationship with another database, IMS HP Load cannot reload a data set in either communication industry standard format or communication industry partitioned format.
  • If the database is a HALDB, IMS HP Load cannot reload a data set in either short header format or communication industry standard format.
  • If the database is a SHISAM DB, communication industry standard format is not supported.
  • If the database is a non-HALDB, IMS HP Load cannot reload a data set in communication industry partitioned format.
IMS HP Load determines which format is being used; you do not have to specify it.
exitname
The name of the user exit routine. Specify this operand if you use the exit interface of IMS HP Load. The specified exit routine must be in the STEPLIB concatenation.
L
Specify this operand only if the user exit routine is to be run under an environment of LE (Language Environment®). This option is effective if the user exit routine is written in Enterprise COBOL for z/OS® or Enterprise PL/I for z/OS. This option is not effective for user exit routines written in assembly language.
