Here is an example of the T (target select) command with PDC (Main Menu item 2):
You see:
PDC = 9876 Action = 1 Data = 201

You enter T 8765 (Return) and see:
> PDC = 8765

Action Groups
Some action numbers are part of groups.
These groups are sets of closely related system
parameters that need to be changed as a group.
For example, when you assign a voice
terminal, you must also assign a PDC. (See the example at the end of this section. ) Action
groups are marked with [AG] in the administration procedures.
The number of actions may vary from group to group, but no group contains more than five
actions.
All action values within a particular group are consecutive. Within a group,
whenever you change a parameter, the system advances you automatically to the next action;
this process continues through the last action in that group.
After modifying a parameter that is part of an action group, you must complete the
modifications to the group by entering data values for the remaining action numbers. This
protects System 25 from acting on partially complete data. When changing data values
associated with these groups of action numbers you automatically advance to the next action
after you change the data value.
You change action numbers with the A command as before.
Note If you change to an action number outside of the group you are currently in, all
the data values entered for that group remain as they were before you began
modifying the group. In other words, if you leave a group (by selecting an action
outside the group) before entering the last data value for that group, all changes for
that group are abandoned.
Here is an example of administering an action group:
You see:
Port = 10408 Action = 1 Data = 0
You enter D 207 (Return) and see:
> Data = 201
Port = 10408 Action = 1 Data = 201
>
Port = 10408 Action = 2 Data = 0
> Data =
Notice in the fourth line of this display how the system automatically brings up the
next member of the group.
