F. Support tools and measurements
There are two separate functions of form creation: forms design
and forms description. Any form can be converted to an
electronic form stored on the system by describing it in Forms
Description Language (FDL).
Forms design involves laying out and measuring a form and is
only a peripheral concern of this guide. A forms design ruler is
provided for the forms designer.
Forms design ruler
The forms design ruler is used for the following:
• Measuring character and line spacings
• Converting forms from one type of paper to another.
The ruler has eight scales, four on the front and four on the
back, as shown in table F-1.
Table F-1. Standard formats and spacings
Side 1 Formats/spacing
Scale 1–10/inch Standard computer output character spacing; can also be used
for measuring inches, graduated in tenths.
Scale 2–6/inch Standard computer output line spacing (6 lpi).
Scale 3–8/inch Standard computer output line spacing (8 lpi).
Scale 4–12/inch Can be used for 12 cpi or 12 lpi.
Side 2 Formats/spacing
Scale 5–13.6/inch Default character spacing on Xerox laser printing systems.
Scale 6–8.1/inch Default line spacing on Xerox laser printing systems (66 lines
per landscape page).
Scale 7–10.7/inch Line spacing on Xerox laser printing systems (88 lines per
landscape page).
Scale 8–15/inch Can be used for 15 cpi or 15 lpi.
The scales can be used for either character spacing or line
spacing. For example, scale 1 can be used for either 10
characters per inch (cpi) or 10 lines per inch (lpi).
