From the keyboard of harichan@eecae.uucp (Ronald Harichandran):
:Is it possible to have an if-then-else-endif block on a single line?
:
:I wish to do something like
:
:if () then
:  command
:else
:  command
:endif
:
:but wish to have it in a single line like
:
:if () then, command, else, command, endif

You can often  work something out using /bin/test and the short-circuit
booleans:

    [ some test ] && success || failure

Evals might be coerced into helping -- haven't thought about that too much.

In general, your happiness with csh will be inversely proportional to how
much you try to do with it.
