Operating Procedures

Assigning a Coax Printer

Each display station in a system configuration can be assigned a Host printer for generating copies of information displayed on the screen. These copies can be used to maintain records of terminal/CPU transactions.

For 104-key and 122-key keyboards, press and hold the Alt key, then press the Ident key

to display the Assign Printer condition symbol ( – – ) on the operator status row. For 102/103-key keyboards, press and hold the Shift key, then press the Ident key to display the symbol.

Note: If	99 appears on the operator status row when the Ident key is pressed,
the	– – will not display. Enter Setup mode and select Host printer

instead of Screen printer or Trimmed Print. This allows you to assign the coax printer.

Consult your supervisor for an available coax printer’s ID number and enter the two- digit number for the printer being assigned. 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 you enter messages through the keyboard, they are displayed on the screen either as unformatted information or according to a program determined format. Attributes of the formatted display screen fields control the amount and type (alphanumeric or numeric) of entered data.

Figure 4-1 on Page 4-4 shows a typical formatted display screen. All fields on the screen are preceded by a nondisplayed attribute character and are defined as protected or unprotected (entry) fields. For protected fields, the application program fills in the information following the attribute characters. Attempts to change displayed information in a protected field cause a “Go Elsewhere” condition symbol

( X ) to be displayed 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.
