• Form Data Switch Character designates the insertion of the form’s
fill–in data. The character, considered a field indicator character, is
always in a range from 2/0 through 7/14. The form–data switch
character must be different from the control–character encoding
character. The form data switch character is not printable within the
form and should not be used in any control sequence in the form.
• Form length is a five digit number, 00001 through 65,000) that defines
the length of the string to follow. The string count includes all character
other than uncoded control characters (0/0 through 1/15).
• Form Data String is the constant portion of the form: the data. Form
data is a string of text and command sequences with encoded control
characters. Terminate the string with an ST command. Uncoded control
characters (other than ESC), act as formatting characters for editors.
Though you can embed them in the form data string, they are not part of
the form.
