In OFP v1.96, comparison of strings is not case sensitive. Example : "STRINGtext" == "stringTEXT" returns true.

(A3 1.16) for case sensitive comparison, array comparison and boolean comparison we can use switch do. e.g. switch (_var0) do { case (_var1) : {true}; default {false}; }; 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; // false And we can use such workaround instead of using BIS_fnc_arrayCompare or BIS_fnc_areEqual
