13.7.1 Character Codes and Creating a Keypad
A keypad is composed of a variety of function
keys with different ASCII codes and special keys
"ENT" (Enter), "BS" (Backspace), "CLR" (Clear)
and "ESC" (Escape).
By creating one function key then duplicating it, changing its character code and arranging the keys in a regular pattern, a
keypad can be created. Since any character can be assigned to a function key, specialized keypads can be made for any
application. Keypads can be saved in the Group Library for use wherever needed.
A typical Numeric keypad
consisting of 0~9,
'.','-', CLR, ESC and ENT
Keypads are used with the Numeric and ASCII Input Parts to change their values. As the first key is pressed the displayed
value is cleared and new data entry begins.
Special Key Functions:
CLR key Sets the displayed value to 0 or blank.
BS key Erases previously entered characters from latest to earliest.
ESC key Ends data entry without changing word values.
ENT key Ends data entry and saves the displayed value to the word.
Note: Both the ENT and the ESC keys reset the System Reserved bits LB9060 - LB9069 to zero.
