Parameter Type

Keyword, optional

Purpose

Use the ACCODE parameter to specify or change an accessibility code for an ISO/ANSI/FIPS Version 3 or ISO/ANSI Version 4 tape output data set. An installation-written file-access exit routine verifies the code after the code is written to tape. If the code is authorized, the job step’s program can use the data set; if not, the system issues messages and may abnormally terminate the job step.

A data set protected by an accessibility code should reside only on a volume protected by RACF® or a volume accessibility code. The volume should not contain any unprotected data sets.
