IST772I

Explanation
 VTAM® issues
this message as part of a message group. The first message in the
group is IST755I. An alert has been received with a user action code
(UAC) of uac. Any qualifiers that were contained
in the alert will also be displayed (from 0–3 qualifiers).  Notes: The qualifier text is printed if qualifiers are received with
the alert. For example:  If two qualifiers are attached to the alert, VTAM will not display the Q3 = qualifier3 text.
If no qualifiers are attached to the alert, VTAM will display only uac.

If VTAM displays a UAC
that is not listed below, VTAM does
not recognize the UAC. See IBM 3720/3721
Communication Controller Daily Task and Problem Determination for
information regarding UACs not listed in this manual.
