• In ArmA3 ver 1.16 Please note the difference between for forspec and for do, for forspec detects Boolean in each scope while for do doesn’t. e.g.

command	Structure	Summary
for forspec	a= 0; b = true; for [{_i = 0},{_i < 10 && b},{_i = _i + 1}] do { a = a + 1; if (a >= 7) then {b = false} }	loop can be exited via Boolean control, possible workaround can be like BIS_fnc_areEqual
for do	a= 0; for "_i" from 0 to 10 do { a = a + 1; if (a >= 7) exitwith {} };	have to be exited via exitWith

• Never try to tell a decimal number via binary number in a loop; otherwise the loop will be infinite:

for [{_a = 0},{_a != 1},{_a = _a + 0.1}] do {}; //an infinite loop; _a will never be 1 so the scope will always be true. Any binary number behind the decimal point is always the sum of 1/2, 1/4, 1/8, 1/16 etc. so decimal number with odd denominator like 1/3 or 1/10 cannot be exactly equal to each other.
