one more question, why if I use \setRTL at the beginning of the document it does not works which is defined as
\newif...@rtl \...@rtl\pagedir TRT \bodydir TRT \pardir TRT \textdir TRT \else \pagedir TLT \bodydir TLT \pardir TLT \textdir TLT \fi \def\setrt...@rtltrue} \def\setlt...@rtlfalse} but if I just say \pagedir TRT \bodydir TRT \pardir TRT \textdir TRT at the beggining of a document, it works. Should not these two work the same?
