Dears, Please check (and use it, if you want) this paquet of macros I've writed in order to help writing a more readable source code in MPASM. They're macros for write structured programs, like IF - ELSEIF - ELSE, WHILE and REPEAT - UNTIL. They can be nested (10 levels). http://www.geocities.com/sesabu/pic Sergi Sanchez Barcelona Tecnologia S.A. http://www.piclist.org/techref/member/SSB-BTSA-ES -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
