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 predefined 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, # must be one, but LEN and PARM can be
either 1 byte or 2 bytes in length (the 2-byte PARM length is supported
in z/OS V1R12 and above). These PARM values are new for the TS1140:
