Use setenv.  (See csh(1)).

Variables defined using setenv are available in child processes.  The
syntax of setenv is different from set, God only knows why.  Look also
at the 'Variable substitutions' section in csh(1), as there are
limitations on the use of : modifiers if a variable is an environment
var rather than a shell (set) var.  If you have the same name both
'set' and 'setenv'ed in a process, the 'set' definition should win.
(So, if you need to use : modifiers on env'ed vars, you need to arrange
for the child process to do something like:

set fred $fred

(Assuming fred is not already 'set', the 'setenv' value will be picked up.)
