	      o  Font changes using

	      o  Size changes using

	      o  Macros that come in open ... close forms, such as the and macros, which must appear in matched pairs.

       knows about the and macro packages.

       for  and  commands,  in which each is terminated with and each is terminated with Although text files format properly when the next font or
       point size is coded directly instead of using or such techniques produce complaints from checknr.  If files are to be examined by  checknr,
       the and delimiting conventions should be used.

       cannot be used to define single-character macro names.

       does not recognize certain reasonable constructs such as conditionals.
