Variable messages can be displayed or printed by setting a predefined field TEMPn to the required message and entering TEMPn in place of a message in the MESSAGE statement.

When a message occurs, the image is redisplayed to the user with the message on line two of the status surface. If more than one ERROR, WARNING, or MESSAGE statement is executed, the user can display the additional messages.

In output processes, messages are printed on the report; in update, status, and subroutine processes they are printed to a log.
