/DECIMAL_SIZE

  The /DECIMAL_SIZE qualifier lets you specify the default size  for  packed
  decimal  data.   You  specify the total number of digits in the number and
  the number of digits to the right of the decimal point.

  The format of the /DECIMAL_SIZE qualifier is as follows:

     /DECIMAL_SIZE=(d,s)

  where:

     d              is the total number of digits in the number.

     s              is the number of digits to  the  right  of  the  decimal
                    point.

  The default decimal size applies to all decimal variables  for  which  the
  total  number  of  digits and digits to the right of the decimal point are
  not explicitly declared.  See the HP  BASIC  for  OpenVMS  Alpha  and  VAX
  Systems  Reference  Manual  for  more  information  about  packed  decimal
  numbers.

  The default is /DECIMAL_SIZE = (15, 2).
