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
