Thank you for your response. I guess this partially work, but I was more looking for an error prompt to the user like:
Code:
cluster_on_lev3.csh -dir /home/shared -t 2.3 -p 0.05 -c26  -l2 
"Incorrect use of argument"

Thank you for your help!

So, change the text "unknown option" into "incorrect use of argument"...

Unfortunately the error message which i get is:
Code:
argv: Subscript out of range

I use ksh and bash; not csh. And, I strongly prefer utilities that accept, but do not require, space between an option-letter and its option-argument. But, if I understand what you're trying to do, just change:
Code:
	case "-h":
            set zmax = $argv[1]; shift;
	    breaksw
	endsw

to:
Code:
	case "-h":
            set zmax = $argv[1]; shift;
	    breaksw
        case "*":
            echo "Incorrect use of argument: $flag"
            breaksw
	endsw

Code:
while ( $#argv != 0)
	set flag = $argv[1]; shift;
	switch ($flag)
	case "-dir":
	    set lev3cope = $argv[1]; shift;

Code:
	case "-h":
            set zmax = $argv[1]; shift;
	    breaksw
        case "*":
            echo "Incorrect use of argument: $flag"
            breaksw
	endsw

Besides its CSH which i dont know, i'd understand the 'set' line, as the variable "flag" becomes the value of the array argv[1].
Which in turn would let you use $flag over $argv[1] on each call, or am i misunderstand that set flag = argv[1];shift

Took me just 10 years to get near the though i'd finaly understand 'shift', but this line.

Just trying to learn.
