    hello:

    There is some way to declare variables to detect if a change has occurred in them and to undertake an action, method or execute ST command.

    Best Regards

    or

    xExecute := (myVar <> oldMyVar);
    oldMyVar := myVar;

    hello:

    Very thanks, but my question was oriented to whether there is a property that you can give to some points to know that they have modified their value, or to launch an action when one is modified.

    Best Regards,
