State Data Files RY 98

The data contained in each of the files are comma delimited (a comma is placed between each data element). In cases where a comma is part of the data, quotation marks (" ") are used around the data element so as not to confuse it with a field delimiter. The files all have the *.txt extension, but can be opened with most spreadsheet programs or PC-based database applications. (The National file is too large to be read into a spreadsheet. You must use a database program or some other method.)
