If ever have more than 256 actions, will have to change this.

Since WM_COMMAND IDs must be shared among all menus and controls, they are carefully conserved, especially since there are only 65,535 possible IDs.

Formerly UCHAR, but since UCHAR doesn't actually save memory yet, a UINT for performance reasons.

For use with GetKeyJoyState(), etc.

The first timers in the series are used by the MessageBoxes. Start at +2 to give an extra margin of safety:

FAIL = 0 to remind that FAIL should have the value zero instead of something arbitrary because some callers may simply evaluate the return result as t

These are used for things that can be turned on, off, or left at a neutral default value that is neither on nor off. INVALID must be zero:

Forward declaration since classes use each other (i.e. a menu *item* can have a submenu).

WM_USER is the lowest number that can be a user-defined message. Anything above that is also valid. NOTE: Any msg about WM_USER will be kept buffered

But the array that goes with these actions is in globaldata.cpp because otherwise it would be a little cumbersome to declare the extern version of the

Same reason as above struct. It's best to keep this struct as small as possible because it's used as a local (stack) var by at least one recursive fu

Style reminder: Any POD structs (those without any methods) don't use the "m" prefix for member variables because there's no need: the variables are a
