I seemed to have it working sorta when I run it and save the results I am noticing that in spe it spaces correctly but when I save it to a file I can open it in wordpad there is only one line. when I open in up in WinXound (A csound editor) it is double spaced. if I do it in a batch file the output file is spaced correctly.. when I do splitlines it is giving me one charecter down the page as output.. Do I need to do something or can I do something to put an end of line charecter in the output??
