	Here's a untested quick hack....It's not pretty, but it does
	what you are asking for.  (* smile *)  Let's see how many more
	prettier ones will be sent after this.  *8-)


#! /bin/csh -f

#
#  compress and execute.  Simple and sweet.  Could be done better
#  but this does it as well as needs be.  (Didn't really need the 
#  `date` part, but just playing it safe.
#

set argc = $#argv

if ( $argc !=  1) then
   echo "Usage:  cx prog"
   exit(1)
endif

set DATE = `date`
set FNAME = "$1$DATE[4]"

cp "$1.Z" "/tmp/$FNAME.Z"

uncompress "/tmp/$FNAME.Z"

"/tmp/$FNAME" 

rm "/tmp/$FNAME"
