Hello all,, , 

I've made tcsh script that uses a environment variable that can be defined or 
not, the script works, but if the variable is not defined i get the message
  'carrotcount: Undefined variable.'

from the example script below . . .

#!/usr/bin/tcsh
echo $carrotcount

My question is : is there a way to suppress the 'undefined variable' message 
or can i check wether it is defined (in a tcsh script) . . 

Grtz Dries Pruimboom
