Nothing at all, I believe, but the convention is for tab characters to be interpreted by an output device as moving the cursor to the next tab stop/alignment column. In the absence of any custom set of tab stops, the convention is to space them evenly every 8 characters. So, WinHugs is being unnecessarily non-standard to interpret "\t" as being a shorthand for 8 spaces. I've changed this to have it fall into line with the conventional interpretation & checked in the tweak. Thanks for reporting this. --sigbjorn _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell _______________________________________________ Hugs-Bugs mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/hugs-bugs
