Just use the following from betaenv:

   (************** Command line arguments *****************)
   
   NoOfArguments: (* Return number of arguments on command line *)
     (# noOfArgs: @integer; <<SLOT NoOfArguments: DoPart>> exit noOfArgs #);
   Arguments: 
     (* Returns argument number argNo. 
      * Note: argument number 1 is the command itself.
      *)
     (# argNo: @integer; theArg: ^text;
     enter argNo
     <<SLOT Arguments: DoPart>>
     exit theArg[]
     #);
