Read variables from a text file for use in csh script

Hello,

I have a text file (say, declarevars.txt) that contains multiple lines that are essentially meant to be variable declarations:

Code:
set arr1 = (var1a var1b var1c)
set arr2 = (var2a var2b var2c)
.
.
.

I want to be able to read this text file within a csh (sorry) script and have that script treat these lines as if they are part of the script. That is, after reading the text file, if I write

Code:
echo $arr1

within the script, it would print out
Code:
var1a var1b var1c

My reason for doing this instead of setting the variables within the script itself is more for neatness and convenience. I would be using a lot of different scripts doing different things but each would be using these same variables and I didn't want the first 50 lines of each script to always be variable declarations.

Based on what I've found from forums, I have tried the following

Code:
`cat declarevars.txt'

and
Code:

foreach line ("`cat declarevars.txt`")
end

However, none of these seem to work. I am hoping that someone can help me with this question. Thank you very much!

file1 file2 file3 DESCRIPTION
compares three versions of a file, and prints disagreeing ranges of text flagged with these codes: all three files differ file1 is different file2 is different file3 is different The type of change required to convert a given range of a given file to some other is indicated in one of these ways: Text is to be appended after line number n1 in file f, where f = or Text is to be changed in the range line n1 through line n2. If n1 = n2, the range can be abbreviated to n1. The original contents of the range follows immediately after a indication. When the contents of two files are identical, the contents of the lower-numbered file is suppressed. Produces a script for the editor that can be used to incorporate into file1 all changes between file2 and file3 (see ed(1)); i.e., the changes that normally would be flagged and Produces a script to incorporate only changes flagged Produces a script to incorporate only changes flagged Produces a script that will incorporate all changes between file2 and file3, but treat overlapping changes (that is, changes that would be flagged with in normal listing) differently. The overlapping lines in both files will be inserted by the edit script bracketed by and lines. Produces a script that will incorporate only changes flagged , but treat these changes in the manner of option. The following command applies the resulting script to file1. EXTERNAL INFLUENCES
