Using CASE Statements in an MFS Dispatch Routine

A second method to dispatch within the MFS is to use a CASE block. In this method, the value of CODE is tested in a series of CASE statements to determine the logic to be executed for the operation. For example, this code fragment illustrates a portion of the CASE logic:

BEGIN CASE

CASE CODE = 1

  (read logic here)

CASE CODE = 2

  (read-only logic here)

CASE CODE = 3

  (write logic here)

  (etc.)

END CASE
