Before you begin

A user access profile must give you authority to create a Descriptor List.

You must have created a Descriptor List data set. The following attributes are recommended:

  • RECFM=FB
  • LRECL=80
  • BLKSIZE=multiple of 80

To Create a Descriptor List

  1. From the ETA Main Menu, type 2 in the Selection field and press Enter. The Descriptor List Edit/Execute Entry panel is displayed.
  2. Verify or change the IMSID or Group name. To change the IMSID or Group name, type the new IMSID or Group name in the IMSID or Group field.
  3. Type 1 in the Selection field.
  4. Type the name of the new Descriptor List in the Descriptor List member field.
  5. Verify or change the name of the data set that contains the ETA Descriptor Lists. To change the data set name, type the new name in the Descriptor List library field.
  6. Press Enter. The Edit Descriptor List panel is displayed.
  7. Type the I action code in the A selection field and press Enter. The Insert Descriptor pop-up window is displayed.
  8. Specify the descriptor you want to create.
    1. Under the Select the type of descriptor to create heading, specify the type of descriptor that the Descriptor List will add.
