Description

The LASTKEY() function returns the ASCII code for the last key which was pressed at the keyboard. If the optional <expN> is passed, the next LASTKEY() return value will be set to this value. This function is useful for returning the key pressed in response to the DIALOG MESSAGE command. The LASTKEY() function can also be used in conjunction with the CTRL() function for terminal independent programs. The CLEAR TYPEAHEAD commands clears the LASTKEY() function to zero.

When used in Recital Mirage in conjunction with INKEY(<expN>,"M"), LASTKEY() returns a numeric value indicating the last mouse operation as shown in the table below.
