Hi again,
Thank you for your suggestions.
I was able to write and read to a file. Just one more thing, how do I check
for end of file?
I have to read the file and print the data onto a report.
Thank you,
Celia

Hi Again: If you are going to be writing often to your file you will want to
use the
FileInfo Class instead of the File Class. It is pretty much the same except
that it is an instance class, it does not require a security check every
time it is called and can be made threqad safe me thinks.If you are just
logging errors or something that you don't care about performance with then
the File class is the way to go since you will not have to instantiate the
class in your code but it will run slower.
