The autoinstall control program at DELETE

To provide symmetry of control over the autoinstall process, the autoinstall control program is also invoked when:

Input to the program is through a communication area, addressed by DFHEICAP. The layout of the communication area is shown in Figure 36.

Figure 36. Autoinstall control program's communication area at DELETE for consoles
    Fullword 1         Standard Header
      Byte  1          Function Code           (X'FE')
      Bytes 2 - 3      Component Code          Always 'ZC'
      Byte  4          Reserved                Always X'00'
    Fullword 2         Terminal ID of console being deleted
    Fullword 3         Consolename of console being deleted
      Bytes 1-2        Deleted consolename length
      Bytes 3-4        Start of deleted consolename ID
    Next 6 bytes       Remainder of deleted consolename ID

The parameter list contains the following information:

  1. A standard header, where byte 1 indicates the request type (this is hexadecimal character X'FE' for DELETE), and bytes 2 to 3 contain the component code, which is always ZC for consoles.
  2. The second fullword contains the termid of the console that is being deleted.
  3. The third fullword contains, in the first two bytes, the length of the deleted console name and, in the last two bytes, the first and second characters of the console name.
  4. The last 6 bytes of the communications area contains the remainder of the console name (third to eighth characters).
