	Option	Definition
	name	Identifies a previously specified graphic that is currently subject to the HOLD
		parameter of the command that specifies it.
		Refer to the “IMAGE DJDE” section later in this chapter.
	vpos	vertical position.
		Specifies the vertical position of the top edge of the graphic, relative to 0,0 on
		the current physical page
	hpos	horizontal position
		Specifies the horizontal position of the left edge of the graphic relative to 0,0 on
		the current physical page. The form of the specification (UN, CM, IN, DOTS, or
		XDOTS) is the same as for vpos.
	n/d	numerator / denominator
		Specifies the reference scale factor. Each DJDE, n and d, must be an integer in
		the range of 1 to 8, thereby allowing a reference scale factor in the range of 1/8
		to 8. The reference scale factor is multiplied.
	unit	Unit of measure for the vertical and horizontal positions. Options are:
		•	CM (centimeters)
		•	IN (inches)
		•	DOTS
		•	XDOTS
		• UN (user defined units).
			If UN is specified, the user defined positioning unit must previously be
			defined by the UNITS parameter of the OUTPUT command in the current
			JDE or JDL.
		NOTE: IN and CM are each specified as a decimal number with up to three
		digits to the right of the decimal point.
		The default unit is IN.
			ALTER DJDE: point to note
			ALTER maintains the GRAPHICS HOLD parameter in effect but
			also specifies a new set of imaging parameters for the current
			and subsequent pages.
			Examples of ALTER DJDE
			ALTER=(BUS,5,5,1);
			ALTER=(IMG,1,3,5), END;
