This package includes an alternative version of the source code 
named vecxalt.bas. 
It's the original source code altered so that player can
fire rockets more efficiently(INKEY$ statement was a poor
choice). To fire rockets when running the alternative source
code press ENTER(don't hold it; repetitive clicking is more 
efficient). In the documentation it's said that the middle mouse
button does the missile firing but it didn't work with my mouse.
Therefore this change. Also, in the original source code you 
couldn't exit the game. Changes made by Lachie Dazdarian.

L.D. August, 2005.
