Oh, poppycock. C-Shell is perfectly fine for programming scripts.
It's just that you can't give ksh syntax to the csh.
Really more a matter of what you are used to than anything else; that
square-bracket gibberish gives me the heeby-jeebies.
Anyway, in csh:
#! /bin/csh
# whatever the count was here; I forget
set count = 327
while ($count > 0)
echo hello
@ count--
end
which is to my mind a lot more readable and C-like (thus the name, "csh").
