Suppose one has a file containing names of other files like this:

data.0001.rle
data.0020.rle
data.0025.rle
data.0085.rle

From a C-shell script, I would like to, one-by-one, get the names out
of this data file and do something with them like this:

#!/bin/csh -f
#
#
foreach file (my_file_list)
   echo $file
   process $file
end

Does anyone know how I do that?

where $1 is the name of your list file 
in the scipt call:

#!/bin/csh -f
#
#
foreach file (`cat $1`)
   echo $file
   process $file
 end
