In menu mode, MSGMAKER provides one or two masks for each function. In each mask, the user can
select a function by entering alphabetic or numeric characters or marking it with “X” and start the function by pressing the DUE key
initiate control functions by pressing the function keys F2, F3, K1, K2 and K3
deviate from the defined processing sequence of the masks and call any function by entering statements in the command area. Selective control of the individual masks enables the user to move through the masks more quickly, thus reducing the time taken to process a message file (see also "//GO-TO - Branch to specified mask").
call any statement with the help of SDF. SDF is in EXPERT mode; if you enter a question mark, SDF displays all the available MSGMAKER statements.
