The reason that I wanted to use error codes is that they fit better into
overall error handling. There are several reasons for this. first, there
are more error codes than just in file i/o, which is all that there are
IEStatus codes for. (There aren't even enough status codes for all the
i/o errors.) Second, using errorcodes allows for a function that has some
calls returning IEStatus, and some returning errorcodes. I think that
both of the functions I've worked with that used IEStatus have been like
this. In short, IEStatus just is not as flexible as UT_ErrorCode.
Just to clear up any misunderstanding, I did not create error codes, even
though I have written most of the code that handles them (I think). There
were already two defined when I started about 10 days ago.

I used lower case because the creator of UT_ErrorCode had. If that should
change, I could do that fairly easily.

See above.
