ASCII Entry Controls

ASCII entry controls let you send an alphanumeric string (up to 128
characters) to a controller. Like numeric entry controls, the ASCII entry
control can appear on a screen as a keypad enable button or a cursor
point. When either object is activated, the ASCII scratchpad opens.
The look of the scratchpad depends on the terminal.

ASCII Scratchpad - Keypad or Keypad/Touch Screen Terminals

Select characters from the Character Keyboard by moving the cursor
(with the keypad arrows) over a character and pressing the Sel-F1
function key. The character appears in the Display Area. This area
scrolls so you can enter a string that is longer than the Display Area.
All characters are sent to the controller even if not visible.

After entering characters, press

to send the string to the controller.

The leftmost character is placed in the high byte of the first word (of
the write tag), the next character in the low byte, and so on.

Sends the character string to the assigned write tag address in the controller.

When opening the ASCII scratchpad, the string is highlighted. If you select a character
immediately, the terminal clears the Display Area and displays the selected character. If you press
a control key, the terminal continues to display the existing string, allowing you to edit it.

Toggles between Insert and Overstrike mode. Overstrike mode appears in reverse video. In Insert
mode, the selected character is inserted before the cursor in the Display Area. If the maximum
number of characters is entered in the Display Area, new characters are ignored. In Overstrike
mode, the selected character replaces the character at the cursor in the Display Area.
