The following program, which contains a macro call using the %
operator and a %out in the macro, will not always print out "assume
nothing:"

string  equ <assume nothing>

usestr  macro   str
        %out    str
        endm

        usestr  %string
        .
        .
        .
        .
        usestr  %string

end

   Microsoft is researching this problem and will post new information
as it becomes available.
