discreet integers! I could suggest that: 202.76.345.2 is a tuple, not a integer. Or it could be: 202.76°C and: 345.2°C with a mistakenly typed "." instead of a comma. Or it could be: 202.76°F to: 345.2°F and intended to be a range of temperatures, but the keyboard stuck on the second ".". This could be a tag!: <WON:387463> in HTML or XML. This could be formula (less than or '<), written without spaces: 1234<WON:387463 with a set-word inbetween. The point is that using 'parse with suitable rules and 'load if necessary, is a better solution to the larger problem, you're trying to solve. The larger problem being understanding the special dialect that the human being has used or intended to use. I hope that helps! Andrew Martin ICQ: 26227169 http://members.nbci.com/AndrewMartin/
