' This test program allows MaxMiss misses (10 here) while guessing at
' letters in a mystery word. Only alphabetic keys and Escape are
' allowed, which means no " - " or " ' ". Scoring is primitive to
' test the arithmetic and logic. Each unguessed letter has a value of
' -1. Each correct letter scores +2. If a letter is guessed that has
' already been tried, this counts as a miss without altering the scoring.
' The game pauses after each word is spelled or MaxMiss misses. After
' the MaxWords (5) words have been used, the program would normally
' load a new batch of MaxWords words. Here the same words are used.
' For convenience of testing, <Esc> exits the program.
