But +myString is entirely safe, by definition, where myString looks like a decimal number. One just needs to be sure that the preceding character is not a +, AFAIR; I would always use whitespace or = there. Using anything other conversion, except where necessary, is either mere bloat or pandering to uninformed and unintelligent readers. Newbies should note that is often unwise to use ANY of those methods on a string directly typed in to a control without first checking the format of the string with a Regular Expression; and that, after suitable checking and in ordinary circumstances, any of the methods will work well. -- (c) John Stockton, nr London, UK.
