   124 %
   125 % The mathcodes for the letters A, ..., Z, a, ..., z are changed to
   126 % generate text italic rather than math italic by default. This makes
   127 % multi-letter identifiers look better. The mathcode for character c
   128 % is set to "7000 (variable class) + "400 (text italic) + c.
   129 %
   130 % For NFSS the mathcode is "7000 (variable class) + (hex)\itfam + c
   131 % \itfam is probably equal to 7.
