FORMATS
Data to be printed on the GE-235 High-Speed Printer is transferred from memory to the printer
controller.
Three methods f o r arranging horizontal line format for printing a r e available; these
methods may be used in any combination.
1.
Initial setup on the data to conform exactly to the print line desired;
2.
Rearrangement of the data in memory by programmed insertion o r deletion of characters;
3.
Automatic editing performed by logic in the printer controller, based on a combination of
related data and format words transferred to the printer controller. Editing includes zero
suppression, deletion of data, insertion of constants and spaces, and dollar amount field
editing. Many program steps and the inherent mechanical limitations of wired plugboards
a r e eliminated because of the powerful automatic editing capability.
Slewing can be accomplished by program o r switch control. The programmer can cause slewing of
any number of lines up to 63 by specifying the number of lines to be skipped. Paper can be slewed
to the top of apage by either program o r manually pressing the Slew Top Page switch on the printer
control panel.
Special vertical formats can be printed by specifying slews to any one of eight
chanriels of a perforated tape loop (vertical format tape) contained in the printer mechanism.
Editing of Data with Automatic Format Control
When a line is to be printed under format control, format words a r e stored in the Central Proc-
e s s o r memory in a block of words organized the same a s the print line data. The format control
data consists of:
Any printable character
control characters
The Printer Controller, in assembling a formatted line, reads in from memory one data word and
one format word.
The first format character is considered initially. If i t i s a printable char-
acter, it i s printed.
If
it is a control character, it is treated a s described below.
Five characters a r e available f o r controlling the format of the printed line. These characters,
their octal representations, and their functions are:
IGNORE (OCTAL: 35). On Ignore, the next data character i s immediately considered.
IGNORE/SKIP (OCTAL:
36).
On Ignore/Skip, a blank i s printed and the next data character i s
considered.
DELETE (OCTAL:
37).
On Delete, the next data character i s ignored, and the next character
considered is the next format character.
DELETE/SKIP (OCTAL:
56).
On ~ e l e t e / ~ k i p , a blank is printed, the next data character is
ignored, and the next character considered i s the next format character.
