Help with here; supplying data to interactive prgm

[Eric E. Snyder]

This is my first post... hope this is the right place!

I am trying to write a script which supplies data to a number of 
interactive programs.  I have gotten this to work in the simplest
case but I need to be able to expand shell variables for input to
those programs.  

This works although it seems a but contrived:

#!/bin/csh -f
# This is a simple script to matchwater and ancillary programs
# a set of two files. File names are taken as command-line 
# arguments.   
#
echo 'preparing input files with splitwatpdb' 
foreach file ($argv[*])
	echo $file
	splitwatpdb << + 
$file.pdb
$file.pro
$file.wat
+
end 


The next program requires a loop to input the files since it requires
a couple of different files for each $file (ie .pro, .lcd, etc.). This
DOESN'T work and I which it did; there has got to be a better way!

echo 'finding lowest common denominator'
echo ''
# making here doc for lcd
echo $#argv > ~/tmp/lcd_args 
foreach file ($argv[*])
	echo $file.pro >> ~/tmp/lcd_args
	echo $file.lcd >> ~/tmp/lcd_args
	end
lcdpdbauto << ~/tmp/lcd_args



Any suggestions?
Thanks!
