Vectors provided for the ATTN(CNOS)

z/OS Communications Server: SNA Programmer's LU 6.2 Guide
SC27-3669-00

When VTAM® schedules the ATTN(CNOS), VTAM may provide information about the session in the application's VTAM-APPCCMD vector list if the application has provided the address (VTRINA) and length (VTRINL) of a vector list area for the session. The following vectors may be available for the application to examine on the ATTN(CNOS) exit:
  • Partner's DCE capabilities vector (X'12')
  • Name change vector (X'18')
  • Partner's application capabilities vector (X'1A')

For more information about vectors in the VTAM-APPCCMD vector list, see Vector lists used during APPCCMD processing.
