% You can print probe-texts or tables of fonts of choosen families.
% The interactive mode is activated if you type on command prompt:

% Usage:  tex ofstest [file1, file2, ...]
%    or:  csplain ofstest [file1, file2, ...]
%    or:  tex ofstest
%         * <enter>
%
% and follow the notices on the screen.
% 
% You can \input this macro in your document. 
% The interactive mode is disabled automatically in this situation. Example:
%
% \input ofstest [a35]
% \cfam Times   \tables \text \mixed 
% \cfam Courier \tables \text \mixed
% \end

{\nopagenumbers} % usage:  tex ofstest [a35]  or  csplain ofstest [a35]

   If the family is choosen as * then the commands^^J

   {\bf Example.} We try to combine the normal variant with the bold

   The best selection to mark the text is the {\it italic}, not so good
   one is the {\bf bold variant} and somewhat unsuitable
   one is the {\bi bold italic variant}. The marking of the text by
   underline or by letter spacing is totally unsiutable. 
   {\it The marked text have to be good distinguised while reading

   use the italic, if this variant is ready in used font family.
