For script comparison we need to detect whether scripts are running in advance, then compose both into string:
if (scriptDone _var0) then [{false},{(str _var0) == (str _var1)}];It is recommended to use isEqualTo for all types comparison, which is more functional and as fast as operator. For multiple comparisons:fnc_areEqual = { private ["_b", "_var1", "_var2"]; _b = true; for [{ _i = 1 }, { _i < (count _this) && _b }, { _i=_i + 1 }] do { _var1 = _this select (_i-1); _var2 = _this select _i; if (!(_var1 isEqualTo _var2)) then { _b = false; }; }; _b }; ["A","a","a"] call fnc_areEqual; // falseAnd we can use such workaround instead of using BIS_fnc_arrayCompare or BIS_fnc_areEqual
