The numeric indicator not only initiates numeric mode, it also initiates grade one mode. When grade one mode is initiated by a numeric indicator it is terminated by a space, hyphen, dash, or a grade one terminator (dots 56, 3). In the example under discussion, there is no space, hyphen, or dash after the number. If the grade one terminator is inserted following the number, the ou contraction may be used in yourself. The shortform for yourself can only be used when the word is standing alone.
