965.0. "Probs with meta chars passed to action" by 42441::SHELLEY (Thats all I have to say about that) Thu Sep 07 1995 07:32

    Hello,

    I am helping a customer with a problem he has passing meta characters
    in parameters passed to dcl command procedures.

    He is setting up text in the Event Dialog Box with text followed by the
    meta characters *^ . For example "LOGIN*^" this is so that the rest of
    the line can be translated in the Text parameter in the Parameters to 
    Pass to Action in the Action Dialog Box.

    We are finding that when the parameter is passed to the command
    procedure it contains the literal string including the chars *^ instead
    of the translation of the regular expression metacharcters.

    Is this expected behaviour ? If so how can you translate the
    metacharacters so that they can be passed to a command procedure.

    Thanks for any comments on this.

    Royston,
       This will happen if ENS cannot retrieve the event text, i.e., it
    hasn't been flushed to the file yet. When a controller daemon detects
    an event, the match string from the event definition is passed to ENS.
    When ENS processes the packet, it will call the routine to retrieve the
    event text from the logfile. If this routine returns a NULL pointer, we
    will pass what the controller daemon handed us in  the original packet.
    If we got the text fromt he routine then it will pass that to the
    command file. Image based actions *alyways* receive the match string
    passed to us from the line controller daemon thus it is up to the
    image based action routine to call the CMRetrieveEventText routine.
    routine to retrieve the event text and if that routine r
