Operating Procedures
If the application uses a formatted screen, the following keys can be used for positioning
the cursor:
• Press the Tab key ( ) to move the cursor forward to the first entry position of the
next entry field.
• Press the Backtab key ( ) to move the cursor back to the first entry position in the
current or preceding entry field.
• Press the Skip key (Data Entry keyboards only) to move the cursor to the first entry
position in a subsequent entry field.
For applications using unformatted screens, pressing the Tab, Backtab, or Skip key
returns the cursor to the first available character position on the screen.
Entering Data Characters and Selecting Modes
Alphabetic, numeric, and special characters can be entered to compose data messages on
the screen by pressing their corresponding keys.
After filling the last data line of the screen, the cursor automatically returns to the first
available character position, and entry of additional data may write over any previously
entered characters. To prevent loss of previous entries, transmit the data message to the
CPU whenever the screen has been completely filled with data. Refer to the “Message
Transmitting Function” on Page 4-8 for additional information.
Uppercase characters or the upper characters on dual-character keys are entered by
selecting the Shift or Numeric mode before the key is pressed. On Data Entry keyboards,
enter alphabetic characters in numeric fields by using the Shift ( ) and Alpha ( ) keys
(see “Numeric Lock Mode” on Page 4-6).
Shift Mode
Hold the Shift key ( ) while entering data to select upper characters on dual-character
keys or uppercase characters for alphabetic keys; or press and release to turn off the Shift
Lock feature for keyboards with typewriter layouts. Shift mode is designated on the
operator status row by the symbol.
Press the Shift Lock key ( ) to lock the keyboard into Shift mode. For Typewriter
keyboards, press the Shift key to unlock. For Data Entry keyboards, press the Shift Lock
key again to exit Shift mode. For 102-key keyboards, use the Caps Lock key in place of
the Shift Lock key.
