Multipurpose Indicator "
§177. Use of the Multipurpose Indicator: The multipurpose indicator must be used in the situations below for the specific purposes described and, when used in these situations, it must not be regarded as the baseline indicator:
i.
The multipurpose indicator must be used before a modified expression as an
indication to the reader of impending modification. See Rule XIV for additional information and examples.
ii. The
multipurpose indicator must be used between a letter and a succeeding numeric
symbol to indicate that the corresponding numeral is not a subscript to the
corresponding letter. However, when the letter represents a numeral in a
numeration system to a base other than 10, it must be regarded as a numeral
and, accordingly, the multipurpose indicator must not be used.
