What does word_wrap do? put an \r\n in theãsupplied string at the supplied width? ããI have a working function for this, and seems to running just fine now...ãthough that console.putmsg(word_wrap..........); line you wrote up there was aãlearning experience in itself.ãã---ã þ Synchronet þ The BRoKEN BuBBLE (MDJ.ATH.CX)ã

It could return an array, but if you want anãarray, just do a .split(/[\r\n]+/) or something. That way you get to use coolãstring methods and I don't have to do anything. :-)ãã--- ãSynchronet - Jump on the Web 0.2 bandwagon!ãã---ã þ Synchronet þ My Brand-New BBS (All the cool SysOps run STOCK!)ã

It will not place a newlineãin the middle of a word unless that word is longer than the line width.ãã--- ãSynchronet - Jump on the Web 0.2 bandwagon!ãã---ã þ Synchronet þ My Brand-New BBS (All the cool SysOps run STOCK!)ã

I didn't realize that word_wrap actually added newline characters toãthe string as its return value.. makes sense though. Just never thought aboutãit.
