READKEY()*

Find out which key terminated a READ.
---------------------------------------------------------------------------------

 Syntax

        READKEY() --> nKeyCode  

 Arguments

        None.    

 Returns

        READKEY()   returns a numeric code representing the key that 
                  caused READ to terminate.

 Description

      READKEY() is used after a READ was terminated to determine the exit
      key pressed. If the GET buffer was updated during READ, 256 is
      added  to the return code.

      READKEY() is a compatibility function so try not to use it.
      READKEY() is superseded by LASTKEY() which returns the INKEY()
      code for that key.  UPDATED() could be used to find if the  GET
      buffer was changed during the READ.
