f$ActWatch (f$KontrolleEin)

Activate the Watch-DT for a parameter. From this time onwards, the DT set via f$WatchDT is called every time the relevant value is modified, until the Watch-DT is deactivated using f$DeactWatch or the logic has finished.

As many parameters as desired can be monitored simultaneously.

Please note: the parameter name is usually given as string constants, i.e. in quotation marks. If a string parameter is entered - like in the syntax description - then the value of the parameter entered is considered as the parameter name (as long as it is a string).

Hint:

You do not need to enter this instruction directly in the decision table and you can also use this function interactively during trace mode.
