X This is a version of the game "Hangman" in VAX Pascal which I wrote
X for no good reason (because I felt like it). If you need an example
X of how to call the Run-Time Library routines from Pascal, this will
X do, but don't think of it as an example of good programming style;
X Actually, it's terrible.
X
X Anyway, its a fine version of hangman, although the "dictionary" could
X be larger.
X
X The dictionary is refered to as "WordFile". It is an ordinary text
X file of 100 words, one word per line. Maximum 15 characters per
X word, only uppercase letters (A through Z) allowed.
