Expression

   When you specify an expression, DCL evaluates values based on
   the operations specified in the expression. The values can be
   integers or character strings.

   Some expression operators are conventional mathematical
   symbols, for example, plus sign (+). Others specify logical
   and comparison operations, and consist of letters preceded and
   followed by periods; for example, .EQS. Operators are assigned a
   precedence that determines their order of evaluation. You can use
   parentheses to override this order.

   For additional information on specifying expressions, refer to
   the VSI OpenVMS User's Manual.
