PRB: ON KEY LABEL <key label> KEYBOARD "{ESC}" Does Not Work

 Last reviewed: June 27, 1995
Article ID: Q121961
The information in this article applies to:
  • Microsoft FoxPro for MS-DOS, Versions 2.5x, 2.6, 2.6a
  • Microsoft FoxPro for Windows, Versions 2.5x, 2.6, 2.6a
  • Microsoft FoxPro for Macintosh, Version 2.5x, 2.6, 2.6a

SYMPTOMS

Using the ON KEY LABEL to define another key on the keyboard to act as if it were the ESC key does not work.

CAUSE

Issuing the command ON KEY LABEL <key label> KEYBOARD "{ESC}" at the Command Window or in a program will cause the following error:

in FoxPro for MS-DOS: 

                         Interrupted
                 <Cancel> <Suspend> <Ignore>
in FoxPro for Windows, and FoxPro for Macintosh: 

                       Program Error
                        Interrupted
                 <Cancel> <Suspend> <Ignore>
This error is caused because the ON KEY LABEL routine thinks that it is being interrupted and asks the user to Cancel, Suspend, or Ignore itself.

RESOLUTION

To enable the ON KEY LABEL to define another key on the keyboard as the ESC key without generating an error, add the PLAIN clause: 

   ON KEY LABEL <key label> KEYBOARD "{ESC}" PLAIN
By adding this clause, you tell FoxPro to place the literal key label into the keyboard, not the key assignment. It is the key assignment that causes the error to occur.
