Defines the logical record. Unless the IOAREA clause is specified (see below), the field values used to update the database are taken from the area in program variable storage reserved for the specified logical record. Logical-record-name must specify a logical record defined in the subschema.
Identifies an alternative variable-storage location from which the field values are to be obtained to perform the requested modification. When modifying a logical record that was retrieved into an alternative location in variable storage, you should use the IOAREA clause to name the same location specified in the @OBTAIN request. If the IOAREA clause is included in the @MODIFY statement, alt-logical-record-location must identify a record location defined in the program.
Tests for the indicated path status. Path-status must be a quoted literal or program variable (1 to 16 bytes under z/OS and OS/390 or 1 to 6 bytes under the z/VSE operating system). If path-status results from this @MODIFY statement, the action specified by GOTO=branch-location is performed. See ON Clause in this chapter for details.
Specifies the selection criteria to be applied to the named logical record. See WHERE Clause, later in this chapter, for details.
