Volume Interchange Specification

DALINCHG specifies the media type and track recording technique required for system-managed tape library allocation. Whenever possible, IBM suggests that you use an installation-defined DATACLAS construct name to control cartridge media type and track recording technique. Use this key only when it is not possible to use a pre-defined DATACLAS construct because of the dynamic nature of the program and because the program must control the media type and track recording technique. Contact your storage administrator before using this key.

Note: To specify DALINCHG, your program must be APF-authorized, in supervisor state, or running in PSW key 0-7. The specification of DALINCHG will be ignored if a non-system-managed tape volume is allocated.

When you code this key, # and LEN must be one. These PARM values are new:
