Data Fields for Alphanumeric and Incremental Data
Based upon the requirements of a specific application, three methods are
used to print alphanumeric data on the form: fixed (or prepositioned) data,
overlay data, and dynamic data.
Fixed Data
Fixed data is entered during the Create Form mode as part of the form
definition. It appears as prepositioned information similar to other form
elements. The fixed data is printed on each form in the same location and can
only be changed by changing the form definition. Your company’s name,
address, logo, or phone number are typical examples of alphanumeric data
that can be fixed onto the form.
Overlay Data
Overlay data is variable alphanumeric data entered during the Execute Form
mode by positioning the information with line feeds and spaces into an exact
location. In general, a page of data is overlayed onto a form similar to typing
data in the appropriate blanks of a preprinted form. Each page of overlay data
is separated by form feeds to correspond to each form printed. Customer
names, addresses, and order numbers are examples of variable data that can
be overlayed onto the form.
Dynamic Data
Dynamic data is variable data entered by command during the Execute Form
mode. The dynamic data is entered into a location previously defined in the
Create Form mode. Up to 255 locations can be identified during the Create
Form mode as part of the form definition.
A command during the Execute Form mode enters new data in the identified
location(s) each time the form prints. Dynamic data is the most efficient
method of supplying variable data to the form. Again, customer names,
addresses, or any type of variable alphanumeric or bar code data can be
provided dynamically.
