TAPE Naming Conventions

Use the following format to name a TAPE file:

file-id,T,[unit],[unit],[unit],[override]

The following list describes the parts of a TAPE file name:

• file-id

  Specifies the name that identifies this data set in the tape manager catalog or in the HDR1 label on the tape. This is the file ID you specify on the TLBL JCL statement. Range: 1 to 44 characters.

  Note: When the file ID contains imbedded spaces or commas, it should be enclosed in quotes.

  Note: IBM only supports a 17-character file ID in a tape header label. If you have a tape manager, 44-character tape file IDs can be supported. CA XCOM Data Transport does not validate your file ID, but takes whatever you put on the statement and passes it to IBM's OPEN routine or to your tape manager as you have entered it.

• T

  Indicates that this is a TAPE file.

  Note: If you enter a transfer request from a platform that has not yet implemented the extended tape processing parameters or menu interface fields for controlling tape processing to a CA XCOM Data Transport z/VSE server, you must use the T option. You are restricted to standard label tape processing.

• unit

  The physical device address as defined by the CUU parameter on the ASSGN JCL statement. If you are using TAPEM=YES|EPIC, CA XCOM Data Transport ignores any units coded and the tape manager does the tape AVR and assignment. If you are not using the tape manager, the primary assignment is made to the first unit CA XCOM Data Transport finds. Other units found are assigned as temporary alternates.

  This parameter can be omitted if you prefer to use the UNIT parameter to specify a unit or two units (primary and alternate). This parameter can be used in conjunction with the UNIT parameter to specify a primary unit and up to four alternate units that are to be assigned by CA XCOM Data Transport prior to open. Units specified on the statement containing the file ID are assigned before units specified on the UNIT parameter. The unit parameter is ignored because tape processing is only supported when you have a tape manager on your z/VSE system.

• override

  Optional for output files.

  The following override parameters can be specified. The equivalent DFLTAB option is included to describe each override parameter:

  • TMYES to force TAPEM=YES for this file
  • TMNO to force TAPEM=NO for this file
  • TMEPIC to force TAPEM=EPIC for this file

  Note: The override applies only to the processing for the file whose data set name is on the statement that the override appears on. It is in effect for this transfer only.
