hey i was wondering how i would centre text in file. i managed to get the text centred into the run window but when i check the text file its still aligned right...help would be appreciated var streamnumber : int var streamnumber2 : int var words : string var i : int open : streamnumber, "text.txt", get open : streamnumber2, "centre.txt", put i := 1 loop get : streamnumber, words : * put : streamnumber2, words locate (i, maxcol div 2 - length (words) div 2) put words i := i + 1 exit when eof (streamnumber) end loop close : streamnumber2 |

Since a file doesn't have a "maxcol", the best thing you could do is go through all the lines and find the longest line. Set things so that this line will, when everything is "centred", just touch the left margin (ie. don't add spaces to this line). To "centre" other lines, pad them with spaces. |

You'll learn more if you do it yourself than if someone tells you the answer. Give it a try. You may find the String Manipulation Tutorial of help. |

thanks so much it worked like a charm....only one question....sometimes when centreing the number of spaces technically is supposed to be 2.5 so my question is does it actually space 2.5 from the edge or does it just round and go to 3? |

It would put 2 or 3 spaces. Unless your font has a "half a space" character, it's impossible to have half a space. If you're using a monospaced font, it's impossible. |
