Creation password prompt at runtime

[Robert]

hello,
I am sure this has come up before but I could not find it in any of my 
saved list digests.

lookup pps_look=(lf)  k=ke   i=A -Nx

where lf="AGENT" or whatever file I need to lookup into.
This line prompts for the creation password of the AGENT file when the 
code is run.
Is there a way that I can prevent the prompt without removing the password?
I have tried specifying the password for a dummy lookup in the prc table 
but that does not work and PFSP seems to only work for the site password.
Any suggestions?
TIA.
Robert
p.s. the creation password is the same for all of the files I need to 
use, if that helps.
