Default actions of the sample programs

When DFHZATDX or DFHZATDY is invoked at INSTALL of a Client virtual terminal, it:

  1. Accepts the terminal name placed by CICS® in SELECTED_SHIPPED_TERMID.

    If CICS detected no conflict with a currently-installed remote TERMID, SELECTED_SHIPPED_TERMID contains the value pointed to by INSTALL_SHIPPED_TERMID_PTR (that is, the name specified by the Client, or the "VTPREFIX" name generated by CICS).

    If CICS detected a conflict with a currently-installed remote TERMID, SELECTED_SHIPPED_TERMID contains a CICS-generated alias.

  2. Permits the remote definition to be installed by leaving the return code field set to its default value of RETURN_OK, and returning.

When DFHZATDX or DFHZATDY is invoked at DELETE of a Client virtual terminal, it takes no action and returns.
