American Airlines aircraft

Just for the record: I found nothing else that I needed to delete.

Dan/Freddy,

Just wanted to thank you both for taking the time to help a newbie out and get a little understanding of how things work.  I appreciate it.

Regards,

You're welcome, Rob.

One thing that I didn't take the time to point out that I should have pointed out is that, when two or more files contain some of the same data, one has to be careful before assuming one file was the source of the identical data and the other file was the recipient. Data entered via a user interface can be written to two or more files, concurrently. In such cases, all files to which the data was written, were recipients of the identical data. When one or more files receives its identical data from another file rather than directly from user input, one way to distinguish source files from recipient files is to compare the date modified time stamp of the files. On more than one occasion, I've been surprised to find that the file I assumed was the data source, was actually the data recipient (as disclosed by its more-recent time stamp}. When file time stamps (as shown in Windows Explorer) are identical, it may mean that user input was written to the files concurrently, or it may mean that one file was the recipient of the data from another file during the same minute. If the latter is the case, determination of source and recipient will require further testing.
