Integer

   DCL treats all numeric values as integers. If you do not specify
   an explicit radix, numeric values are interpreted as decimal. You
   may specify an explicit radix as follows:

      %D1000 decimal radix
      %O1357 octal radix
      %X12AF hexadecimal radix

   No blanks are allowed between the radix symbol and the number.

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