/TYPE_DEFAULT

  The /TYPE_DEFAULT qualifier lets you specify the  default  data  type  for
  numeric variables.

  The format of the /TYPE_DEFAULT qualifier is as follows:

     /TYPE_DEFAULT={INTEGER }
                   {REAL    }
                   {DECIMAL }
                   {EXPLICIT}

  Specifying EXPLICIT means that all program variables  must  be  explicitly
  declared  in DECLARE, EXTERNAL, COMMON, MAP or DIM statements.  Specifying
  INTEGER, REAL, or DECIMAL means that variables  and  data  which  are  not
  explicitly  declared  default  to  integer,  real  or  packed decimal.  To
  specify the actual size of  variables  and  data,  use  the  INTEGER_SIZE,
  REAL_SIZE and DECIMAL_SIZE qualifiers.

  The default is /TYPE_DEFAULT = REAL.
