Since, \XeLaTeX\ blindly follows the Unicode -% standard, commands like |\MakeUppercase| produce wrong output. For this reason -% I first need to set up the correct |\uccode|s and |\lccode|s. -% \begin{macrocode} -%<*xgreek> -\message{Package 'xgreek' version 3.1.0 by Apostolos Syropoulos}

Many scholars are familiar with the acrophonic Attic numbering system and the -% the command |\atticnum| can be used to generate acrophonic Attic numerals. -% The acrophonic Attic numbering system, like the Roman one, employs -% letters to denote important numbers. Multiple occurrence of a letter denote -% a multiple of the ``important'' number, e.g., the letter Ι denotes 1, so -% ΙΙΙ denotes 3. Here are the basic digits used in the acrophonic Attic numbering -% system: -% \begin{itemize} -% \item Ι denotes the number one (1) -% \item Π denotes the number five (5) -% \item Δ denotes the number ten (10) -% \item Η denotes the number one hundred (100) -% \item Χ denotes the number one thousand (1000) -% \item Μ denotes the number ten thousands (10000) -%\end{itemize} -% Moreover, the letters Δ, Η, Χ, and Μ under the letter ^^^^^^010143 (a form of Π) -% denote five times their original value. In particular, the symbol ^^^^^10144, denotes -% the number 50, the symbol ^^^^^10145 denotes the number 500, the symbol ^^^^^10146 -% denotes the number 5000, and the symbol ^^^^^10147 denotes the number 50,000. It -% must be noted that the numbering system does not provide negative numerals or a symbol for -% zero. -%\begin{macro}{\@@atticnum} -% Now, let me definite the macro -% |\@@atticnum|.
