Assume you have a CSH file called readlines:
#
while (1)
set x = "$<"
echo $x
end
then if you invoke readlines thus:
readlines <readlines (or some other file to read)
it will read the lines one at a time. I don't have a nice, clean
termination condition, but checking for variable 'x' having a zero
length string as it's value might work ok. Also, if you change the "set x"
line to
set x = `glob $<`
you get x as a vector of "words", and you can check this vector for
having length 0 as a loop termination condition.
