Format: DEFINE KEY key-name AS 'string'

 The string is a string of nokeypad mode commands that define the
 function of the key.  If you want the command to be executed when the
 key is struck, the definition must end with a period. Otherwise, EDT
 will accumulate definitions until the user types a key whose definition
 ends with a period, and then execute them all together.

1  –  ?

 You can use a question mark (?) or question mark and asterisk (?*), in
 key definitions to prompt the user for input.  The ? is replaced by the
 characters read from the terminal before the command is executed.  A
 prompt string enclosed in single quotation marks may follow the ?.  A
 response to an input request generated by a ? must be terminated by
 pressing a keypad or function key, whereas a response to a ?* can be
 terminated by pressing a keypad key, a function key or the return key.

2  –  RESET

 If you define a key as 'RESET' (must be exactly five characters) the
 key will perform the RESET keypad function.  RESET is not a nokeypad
 command.  Do not put a period at the end of the definition.

3  –  GOLD

 If you define a key as 'GOLD' the key will perform the GOLD keypad
 function.  GOLD is not a nokeypad command.  Do not put a period at the
 end of the definition.
