Example 1:

_handle = [] spawn {player globalChat "Hello world!"};

Example 2:

There is no guarantee that spawned scripts will be executed in the same order they spawned: for "_i" from 0 to 100 do { _null = _i spawn { diag_log _this; }; }; // Result: 51,1,2...49,50,0,52,53...100

spawn cannot call other local functions on the same scope as itself.
It can, however, call other global functions: _addOne = {TST=TST+1}; TST_addOne = {TST=TST+1}; _add = { TST=TST+1; player sideChat format ["added: %1",TST]; [] call _addOne; player sideChat format ["called local: %1",TST]; [] call TST_addOne; player sideChat format ["called global: %1",TST]; }; TST=0; [] call _add; [] spawn _add; The call of _addOne from the spawned function does not do anything.

spawn requires a script handle when used in the 2D editor. (A3)
In scripts and in the debug console, it is not required, but very useful for keeping track of running scripts. Having a script handle also makes it easy to terminate scripts at any time.

Since spawn creates a new scheduled environment, having an excess of open threads can make the scheduler queue extremely long, significantly increasing the execution time of each thread. (it takes an extremely large amount of threads, though)

If you want to call a local function which has NOT been created inside a spawned function, then do this: _fncOne = { systemChat"This is _fncOne" }; _fncTwo = { call (_this select 0) }; [_fncOne] spawn _fncTwo;
