Regina Rexx and Zenity on Ubuntu

[Bullet]

I am trying to use Zenity in a rexx script to obtain user's login
password via a Zenity dialog. The dialog works but spits the user
entered login password but to the terminal window. Can someone tell
me how to redirect the password output by Zenity so I can process
without it being seen to the user? Relevent code is on the d lines
below marked with 1>> and 2>> with the variable named "cmd". Any
suggestions for alternative approaches are appreciated. Thanks in
advance.

l=length(s_id)-h+1
s_fid=substr(s_id,lastpos("/",s_id)+1,length(s_id)-h+1) /* strip out
directories to get source fileid */
if pos(".",s_fid)>0 then do
s_fn=substr(s_fid,1,pos(".",s_fid)-1) /* Source filename is

Try one of the following:
/* call zenity as an external function*/
title = 'fred'
switches = '--entry --title="'title'" --hide-text'
ret = 'zenity'( switches )
Say ret

/* Use ADDRESS...WITH and write output to queue */
Address System 'zenity' switches With Output FIFO ''
Parse Pull ret
Say ret
/* Use Address...WITH and write output to stem variable */
Address System 'zenity' switches With Output STEM ret.
Say ret.1

Thank you, Mark,
The 1st one still spits the user entry back to the terminal. The 2nd
two are what I wanted and was missing. I didn't try the stem
approach, but I am it will work the same as the stack approach.
Happy Trails, Rob

Hmm, the first one works here. What version of Regina are you running?

rob@fargo:~$ rexx -v
REXX-Regina_3.4 5.00 30 Dec 2007
The first suggestion works here as well. I just tried it again.
Sorry for the misinformation.
