FORMS DESCRIPTION LANGUAGE
Description commands
Description commands specify the location, size, and
characteristics of the following form elements: lines, boxes,
logos, graphics, form sections, and text.
The following commands are used for entering descriptive form
data:
• LINE
• BOX
• TEXT AT
• TEXT IN BOX
• LOGO
• GRAPHIC.
You can enter these commands in any sequence. For a
discussion of the problems you may encounter when entering
these commands, refer to the “Troubleshooting” chapter.
Location coordinates Specify the locations in terms of the y and x axis coordinates,
measured from the form origin specified in the GRID command.
The form origin is generally set to coincide with the variable data
origin, and the grid units correspond to the character and line
spacing of the variable data. The form origin coordinates are
specified as y=0, x=0.
You can specify both x and y coordinates, or just one coordinate
along the y or x axis. If only one coordinate is given, the axis is
implied in the command.
Symbols for coordinates The following five symbols are used in the description commands
to symbolize different coordinates:
• c
o
Origin coordinate
• c
s
Start coordinate
• c
e
End coordinate
• c
a
Absolute coordinate
• c
i
Incremental coordinate.
The coordinate parameter may be followed by the unit of
measurement: inches (IN), centimeters (CM), or DOTS. If units
of measurement are not given in the command, the coordinates
are in grid units.
Negative coordinates Negative coordinates may also be used. A negative y coordinate
is measured upward from the form origin. A negative x
coordinate is measured to the left of the form origin. For
example, a vertical line starting at x=-1 would appear to the left
of the form grid, as shown in figure 2-1. When you use negative
numbers, be sure to stay within the boundaries of the system
page.
