Form Examples and Exercises 6–12
Multiple page documents must be separated by a form feed. (The “page” of
data includes the Execute command, the dynamic data commands, and the
Normal command.) Using the SFON command (described on page 4–90), a
~FF (form feed) command will allow as many forms as required to print with
the appropriate new data supplied dynamically. When the SFOFF command
is used, send a hex 0C instead of ~FF to print multiple pages with new
dynamic data.
