Purpose: The OPSYS command only applies to Hitachi and Fujitsu operating systems. This command can be used to set flags that inform DIF of the operating system capabilities. Under normal circumstances, DIF correctly sets these flags via the OPSYS operand in the DIF PARM field. This command can be used to override the default operating system capability flags.

The ENABLE OPSYS command will inform DIF that the specified capability is available in the current operating system. The DISABLE OPSYS command will inform DIF that the specified capability is not available.

An OPSYS command without ENABLE or DISABLE preceding the command will list the current operating system capability flags. Entries listed as blanks mean the function is supported.

Syntax: 

ENABLE OPSYS {opfunc}
DISABLE OPSYS {opfunc}
OPSYS
Tip: This command is typically only required for first-time Hitachi or Fujitsu installations that are having problems with product installation. The technical support staff, working with the Hitachi or Fujitsu software support, will provide the ENABLE or DISABLE commands to set the appropriate operating system capabilities flags.

The list of valid opfunc operands follows:

  • AR supports Access Register mode
  • CDSP supports DataSpace
  • CM supports Cross Memory Services
  • CVAF supports Common VTOC Access Facility interface
  • ENF supports Event Notification Facility interface
  • IVSK supports IVSK instruction
  • LPAPROT supports PLPA protect with a flag in the PGTE
  • SJF supports Scheduler JCL Facility interface
  • SSAFF supports subsystem affinity
  • TPROT supports TPROT instruction
  • UCBSCAN supports UCB scan interface
  • UCB4 supports four-byte UCB addresses
  • UCB31 supports UCBs in extended memory
  • XAIO supports XA I/O subsystem

Examples: If directed by technical support, the following ENABLE OPSYS command can be used to inform DIF that the operating system provides a UCB SCAN interface routine.
