Script to Reset all PIOs of Selected Type

Recommended Posts

I cobbled out a little useful general purpose script for resetting all instances within a drawing of a selected PIO. (Ain't VectorScript grand?)

Here it is.

PROCEDURE Reset_All_Like_Selected;
kErrStr_no_select = 'ERROR: Nothing selected.
Select an example of the object type you want to reset and run this script again.';
kConfirm_prefix = 'Are you sure you want to reset all objects of type "';
kConfirm_suffix = '"?';


IF fsactlayer <> NIL THEN
   PIO_name := GetName(GetRecord(fsactlayer,NumRecords(fsactlayer)));
   IF YNDialog(concat(kConfirm_prefix,PIO_name,kConfirm_suffix)) THEN ForEachObject(ResetObject, R IN [PIO_name]);
   END ELSE Alrtdialog(kErrStr_no_select);

PIO_name := GetName(GetRecord(fsactlayer,NumRecords(fsactlayer)));

Interesting bit of wisdom here. I was wondering why NumRecords for the GetRecord index so I played with this one a bit. One works fine....as long as there aren't any other records besides the parameter record attached to the PIO.

Sooo...the parameter record, it turns out, is always the last one in the list of records attached to a PIO, so if there's 2 others attached, NumRecords returns 3 and that's the index for the record that returns the PIO name. Obvious to some I guess, but not me.

Thanks Robert,

Yes, the PIO parameter record will always be the Nth record attached to a PIO that has N records attached. By the way, this is documented nowhere AFAIK and is the result of trial-and-error testing, whence cometh so much profound programming knowledge :)
