Overview
1.5.1 Line Data
Line data - that is, raw data from a computer file including PCC-commands.
•
The raw data can be sent to the LCDS-Module offline from magnetic tape or online from
a channel-attached host or over the network
If you are using the LCDS-Module to create reports or other documents from unformatted
data, several elements are required to complete the job:
•
Variable data. Variable data is the part of the report that changes from page to page.
In the example of an inventory report, the variable data would be the part numbers, de-
scriptions, prices, costs, and so forth.
•
The variable data can be imported from the magnetic tape system in the offline mode
or from a host through a channel interface or over the network.
•
Form data. Form data can include headings, boxes, lines, and graphic image files,
such as signatures or logos. Form data is entered in the form of compiled files.
•
Processing data. Processing data is optional and it allows the operator to control the
output of selected reports, or selected copies of a multiple copy report, for cover-to-cov-
er print processing on any job. For example, you may wish to specify that an inventory
report has 49 pages. You may also decide that four copies without cost information are
needed for distribution to clients. The three command sets described below provide out-
put control:
•
JDE. Gives the operator control over the mechanics of a particular print job. JDE
commands specify for example simplex or duplex printing.
•
DJDE. Enables you to modify the printing environment dynamically. These com-
mands are inserted into the input data stream to modify the command characteris-
tics of the existing job descriptor entry (JDE). DJDEs can take effect on a report-to-
report, page-to-page, and record-to-record basis.
•
CME. Enables you to replace certain parts of a report with predefined static data on
selected copies or to specify font changes within the variable data.
1.5.2 Formatted Data / Metacode Documents
Formatted data is sent to the LCDS-Module from a host-based document composition soft-
ware package, for example, XPPI, XDGI, or PC-based software through the front-end pro-
cessor. These systems are often used for electronic publishing and can produce very so-
phisticated printed documents. Data from these sources come in a form that the LCDS-
Module can already understand.
