FORMS DESCRIPTION LANGUAGE
GRID
Specifies how far apart to space the horizontal and vertical grid
lines. This command also specifies the location of the form
origin with respect to the virtual page origin. All FDL commands
create and place form elements (lines, boxes, and so on) relative
to the form origin.
Syntax GRID UNIT IS format id ORIGIN y unit x unit;
or
GRID
UNIT IS value ORIGIN y unit x unit;
Parameter options format id
Name of a predefined format. The format may be one of the
standard formats listed in the “Standard print formats”
appendix or a user-defined format.
When a format is specified, it automatically provides page
orientation, form origin, and grid unit dimensions. All
predefined formats specify the grid units in lines and
characters per inch. The BEGIN values of the predefined
format are used to place the form origin, unless overridden
by an ORIGIN parameter.
value
If a predefined format is not specified, value is used to
indicate the number of inches (INCH or INCHES),
centimeters (CM or CENTIMETERS), dots (DOTS or XDOTS),
or characters per inch or lines per inch (CPI or LPI) that
specify the size of a grid unit. Size in inches or centimeters
represents the length of one side of a square grid unit.
If the value is omitted when DOTS are specified, 1 is
assumed. If only one DOTS parameter is specified, the grid
unit is the same number of dots in both the horizontal and
vertical dimensions.
y
Specifies the offset value used to offset downward from the
top of the virtual page. If y is not specified, the top edge of
the form is located at the top edge of the virtual page.
unit
Specifies the measurement, in INCH or INCHES, CM or
CENTIMETERS, DOTS or XDOTS, that the form origin is offset
downward from the top of the virtual page. If inches,
centimeters, or dots are not specified in this parameter,
inches are assumed.
x
Specifies the offset value used to offset the form to the right
of the left edge of the virtual page. The coordinate x=0
represents the left edge of the virtual page. If x is not
specified, the left edge of the form is located at the left edge
of the virtual page.
Default If no grid units or predefined format is specified, FMT1
(landscape) or FMT6 (portrait) values are used. If no units value
is specified, INCHES is the default.
Example GRID UNIT IS 1 INCH;
Considerations Inches and centimeters may have two decimal places. Dots must
be expressed in integers only. The values value, y, and x must
be positive numbers.
