NUMERIC directive

The NUMERIC directive allows you to treat a data item as an unsigned integer when it is declared as alphanumeric. You might use this when the data stored in the item is always numeric.

Syntax

$XFD NUMERIC

or

*(( XFD NUMERIC ))

Example

The PATIENT-ID field (now appearing in the database table as the PATIENT column) is defined in the source code as being a text field. Since this field will always contain a number, you may want to define it in the database table as numeric. (Note the use of two directives for the same data item here.)

       FILE SECTION.
       FD  jr-file.
      $XFD COMMENT  This sample file demonstrates directives.

               05  fee                         pic s9(5)v99.

The following table is the result, and, in the database, PATIENT is now of type NUMBER.
