Key translation functions

Progress key codes, key labels, and key functions are interrelated, and Progress provides a set of built-in functions to convert from one to another. Figure 4–2 shows how the conversions work, and which functions to use for each conversion.

Figure 4–2: Progress key translation functions

You can use the KEYCODE function to determine the key code for a particular key. For example, the following function returns the value 127, which is the integer code assigned to DEL. Use the KEYLABEL function to determine the keyboard label for a particular key code:

KEYCODE("del")

For example, the following function returns the value CTRL+G:

KEYLABEL(7).

See the OpenEdge Development: Progress 4GL Reference for more information on the KBLABEL, KEYCODE, KEYFUNCTION, and KEYLABEL functions.
