The weapons menu allows you to activate a specific weapon system, target your
weapons, and fire them upon a target.  The ACTIVE WEAPONS SYSTEM button is the
first button on the menu.  When you select it, a drop-down menu will be drawn
which lists each of the weapons systems you have installed upon this ship.  If
you wish to power up a weapon system, simply select its name.  If you wish to
power down your weapons, select NONE.  

TARGET BUTTON
This button is only displayed if a weapon system is activated.  The value of
targeting a weapon system is that you can lock onto a specific target, either
an enemy ship, a planet, or coordinates in space.  Then, if either you or the
targeted object move, your weapons are still locked on your opponent.
Targeting takes one turn to complete.  Once you have established a target, the
TARGET button will be replaced with either the name of the ship you are
targeting or the coordinates in space you are targeting.  To clear the
targeting computers, simply click on the button where the name appears, and you
can re-target, or simply fire the weapon system.

FIRE BUTTON
Provided you have activated a weapon system, the FIRE button will appear.  If
you have already established a target, then your weapons will fire at that
target during the next turn processing.  If you have not established a target,
then a selection grid will appear on the screen, and you can specify which
coordinates on the screen you wish to fire at.  If you are firing a beam
weapon, such as lasers, you will be asked how many cannons you wish to fire (a
ship can be installed with up to 9 cannons of each weapon system) and a numeric
keypad will appear to get your response.  If you are firing a projectile
weapon, such as a phase missile, then this ship will automatically fire a
single missile at the end of the round.
