Function 5D0Ah          Set Extended Error                           DOS 3.1+

    Sets the error class, location, suggested action, and other
    information that will be returned by the next call to function 59h.

        Entry   AX    = 5D0Ah
                DS:DX = Pointer to an Error structure

        Return  Nothing


    The Error structure contains error information as well as the
    contents of the registers when an error occurred.

    Note
    This function was undocumented before DOS 5.0. The MS-DOS
    Programmer's Reference 5.0 incorrectly states that this call was
    introduced in DOS 4.0 and that the pointer should be passed in
    the DS:SI registers.
