A very fine example on how a missing or incomplete naming convention can/will cause trouble! Personally I would never use for example cString as a variable, I would always precede it with a letter to indicate the scope. I would use lcString for local, pcString for private and gcString for glogal. A field on the other hand I coull call cstring.
