Before and after code used to change
page displayed. Useful for PREV and
NEXT keys that do not use any numbered
function keys.
?SECTION USER-PRE-F1 , TANDEM Executed immediately before function key
action but outside the scope of the
transaction when the action is a SEND to
a TMF service. Can be used to perform
moves to prepare the request message or
to make checks.
If a check fails or some other error
condition is found, you can move a
message into T9154-ADVISORY-MSG-
TEXT in the USER-PRE-F1 section. You
can also set T9154-ADVISORY-MSG-
SEVERITY to a severity level (ERROR,
WARNING, or NORMAL) that determines
the display attributes of the message.
Finally, you can set T9154-USER-
ERROR to Y to prevent the program from
performing this action.
The application’s performance will be
better if you do as much of this work as
possible in the service.
?SECTION USER-POST-F1
.
.
.
, TANDEM Executed immediately after function key
action but outside the scope of the
transaction when the action is a SEND to
a TMF service. Can be used to check
data returned from the service, derive
information dependent on the reply, move
values out of the reply, or set display
attributes for data fields.
This section will not be executed if there
was a SEND or CALL error, or if T9154-
USER-ERROR was set in the USER-
PRE-F1 section.
The application’s performance will be
better if you do as much of this work as
possible in the service.
