Passing output of sed/echo to a variable

I understand how to use a variable in a sed command, but for the life of me I can't get the output into a variable.
I'm making a general function to replace part of a filename with a different string, so:
>>myscript this that

would change:
this_file001.txt to that_file001.txt and
this_file002.txt to that_file002.txt and so on...

here's what I have:
#! /bin/csh -f
foreach i ($1*)
set j = echo $i|sed 's/'$1'/'$2'/'
echo "Moving $i to $j"
#mv $i $j
end

But it gives me a syntax error. I played around with using eval but that wouldn't work for me either. Suggestions? (preferably without taking a new approach to my problem even though I'm sure there are other/better ways to do it)
Thanks....

NWBPSET(1)							      nwbpset								NWBPSET(1)

NAME
nwbpset - Create a bindery property or set its value SYNOPSIS
nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ] DESCRIPTION
nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with As another example, look at the following command line: nwbpvalues -t 1 -o supervisor -p user_defaults -c | sed '2s/.*/ME/'| sed '3s/.*/LOGIN_CONTROL/'| nwbpset With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object 'me'. nwbpvalues -t 1 -o me -p login_control -c | sed '9s/.*/ff/'| nwbpset This command disables the user object me. Feel free to contribute other examples! nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information. Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons. OPTIONS
-h -h is used to print out a short help text. -S server server is the name of the server you want to use. -U user user is the user name to use for login. -P password password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset prompts for a password. -n -n should be given if no password is required for the login. -C By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off this conversion by -C. AUTHORS
