Operating Procedures
Assigning a Coax Printer
Each display station in a system configuration can be assigned a host printer that can
generate copies of information displayed on the screen. These copies can be used to
maintain records of display station/CPU transactions.
For 88-key, 102-key, 104-key, and 122-key keyboards, press and hold the Alt key, then
press the Ident key to display the Assign Printer condition symbol
– –
in the
operator status row. For 102-key keyboards, press and hold the Shift key, then press the
Ident key to display the symbol.
Note: If 99 is displayed on the operator status row when the Ident key is pressed,
– –
does not display. Enter Setup mode and select host printer instead of
screen printer. This allows you to assign the coax printer.
Consult your supervisor for an available coax printer’s ID number and enter that
two-digit ID number. The two-digit number replaces the underscore positions on
the operator status row. Once the printer’s ID number is entered, the sequence
ends automatically.
If an invalid ID number is entered for a host printer, the “What?” symbol ( X?+ ) appears
on the operator status row. If this occurs, press the Reset key and try another number.
Data Entry Function
The data entry function consists of writing data messages in an acceptable form for
computer processing. As messages are entered through the keyboard, they are displayed
on the screen either as unformatted information or according to a program-determined
format. Attributes of the formatted screen fields control the amount and type of entered
data (alphanumeric or numeric).
Figure 4-1 on Page 4-3 shows a typical formatted screen. All fields on the screen are
preceded by a nondisplayed attribute character and are defined as protected or unpro-
tected (entry) fields. For protected fields, the application program fills in the information
following the attribute characters. Attempts to change displayed information in a pro-
tected field cause a “Go Elsewhere” condition symbol (
X ) to appear on the operator
status row. The unprotected (or entry) fields accept new or revised information from
the operator. Some application programs further designate an entry field by displaying
the cursor in the unprotected field’s first character position.
