Printronix ThermaLine Series manual Dir

AFn;L	The optional dynamic data field parameters for
	identifying the alphanumeric string location on a form
	and for designating the length of the alphanumeric
	string. If these parameters are used, the actual text
	cannot be entered during the Create Form mode; it
	must be entered dynamically during the Execute Form
	mode. Dynamically entering data during the Execute
	Form mode permits changes to the alphanumeric text
	without redefining or re±creating the form. To use this
	field, perform the following steps:
	a.	Enter AF.
	b.	Replace n with a number ranging from 1 to 255
		to identify the alphanumeric string location on
		the form. The SR and SC parameters are used to
		specify the exact location of the alphanumeric
		field identified by n.
	c.	Replace L with a number equal to the number of
		characters in the dynamic alphanumeric string
		ranging from 1 to 255.
	d.	Dynamically enter the alphanumeric string itself
		in the Execute Form mode. The length of the
		alphanumeric string must be equal to or less than
		the value assigned to the length (L) parameter.
		Refer to ªExecute Form: Dynamic
		Alphanumeric Dataº on page 4±54.
	e.	If the dynamic data field is used, do not enter the
		ASCII TEXT parameter.
DIR	Optional parameter for rotating a character string. Use
	the following codes to indicate the direction of
	character rotation:
	a.	Enter CW for 90 degree clockwise rotation.
	b.	Enter CCW for 90 degree counterclockwise
		rotation.
	c.	Enter INV for inverted characters (180 degree
		rotation).
