	Right, a good thing to do is have a label to go to at the end:

#!/bin/echo sorry,try:source
if ($#newdir_attempt == 0) then
        echo 'usage: newdir dir_to_make [files to move to dir_to_make]'
        goto nd_end
endif
 
mkdir $newdir_attempt[1] || goto nd_end
set cd_attempt=$newdir_attempt[1]
if ($#newdir_attempt > 1) then
        shift newdir_attempt
        mv -f $newdir_attempt $cd_attempt
        unset newdir_attempt
endif
pl $cd_attempt
 
nd_end:


	this example makes a directory, moves any files you specify
into it, and pushd's the new directory (the pl alias).  Called as:

alias newdir 'set newdir_attempt=(\!*); source ~/bin/newdir_csh'

	It's probably good practice to call the end labels something
different in each script, or you may confuse the shell as to which
"end:" you mean.
