TCSH Scripting Help

Hey. My problem is I am trying to write a tcsh script and I need to insure all my arguments are numerical. My solution to the problem was to do: @ test = $argv[$x] >& tempfile #Where x is the given argument number if ( `cat tempfile` == "@: Expression Syntax.") then echo " Non-numerical input given" endif
The problem seems to lie in the fact that the first command (@ test...) produces error and exits the script. If I remove it the test works fine, but I need that for it to work with any given inputs. How can I get TCSH to continue to run even with the error output? Is there a better way to determine if input is numerical? I have the rest of the script written so I really don't want to change to a different shell for the script.
