What Is A Handle?

[MasterRofl]

I want to learn how to use the HSAS in my coding, but I don't know the first thing to handles. Care to inform me please?

Any Warcraft 3 data type is a handle. Unit, effect, lightning, location, trigger - anything that's not an integer/real/string/boolean basically.

Handles themselves actually are integers when it comes down to it, and that's what makes handle attachment systems possible.

Handle = almost any variable type you find in the Trigger Editor through Variable Editor
ex : unit, item, event, ...

for a full list :

//============================================================================
// Native types. All native functions take extended handle types when
// possible to help prevent passing bad values to native functions
//
type event              extends     handle  // a reference to an event registration
type player             extends     handle  // a single player reference
