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;
Table 5-7. ALTER DJDE options and definitions
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.
