I have written a fairly long (>6000 lines) app. Can someone please explain what this error means, how to locate the offending code, and how to fix it? The full message is "Warning: A value of class "char" was indexed with no subscripts specified. Currently the result of this operation is the indexed value itself, but in a future release, it will be an error."

Thanks!
