7–50 Digital Emulation
Loading Forms Sequence (DECLFM) (continued)
The form record includes a form header that defines form parameters and
size, and the form data string. This information is contained in the format
header and includes:
• ID length is a two digit number (01 – 99) that defines the length of the
form ID.
• Form ID is a string of 1 – 99 printable characters. IDs exceeding 10
characters are truncated.
The control–character encoding character indicates the start of
control–character encoding. The character is always in the 2/0 through 7/14
range and is followed by a two digit hexadecimal number equivalent to the
ASCII value of the control character to be encoded.
Every control character must be entered in its hexadecimal format and
preceded by the control character. Do not embed a control character (0/0
through 1/15) in the form string. The following control characters and their
hexadecimal values are allowable:

All printable characters (except control characters) are encoded in the same
manner. For example, to embed the control sequence: ESC [ 100 ‘, (CSI 100
‘) into the form, replace ESC with the control–character encoding character
(^) and the hexadecimal value for ESC (1B). The form’s sequence is
^1B[100‘.
