Trapping first time a script is run

[Barry Kelly]

Is there a way to trap the first time a script is run for an object (ie the master script)?

I am sure I have read something in this forum but searching has not been successful.

If I remember correctly it might be a "Request ..." but I have had no luck with the help file either.

Basically I want to be able to set an new parameter value based on the value of an existing parameter the first time the object is opened in an existing plan.
But then I need to have the new value completely independent of the original value - which is why I need to trap the first time the master or parameter script is run.

Thanks Juha,
I was on the wrong track with the "request" side of things which was throwing me a bit.
I did search for "First" but must have skipped over this post.
I'll be sure to write this one down for future reference.
Thanks again,
Barry.
