# int _LastError

The _LastError variable contains code of the last [error](/en/docs/constants/errorswarnings/errorcodes), that occurred during the mql5-program run. Its value can be reset to zero by [ResetLastError()](/en/docs/common/resetlasterror).

To obtain the code of the last error,  you may also use the [GetLastError()](/en/docs/check/getlasterror) function.
