REWIND  RATS I/O unit

Rewinds an open RATS I/O Unit, so it can be processed from the beginning again. REWIND is necessary only if you have to run through a single ASCII or binary data file more than one time in a single program. This is a rare situation. Most formats, such as spreadsheets, are always read as a whole each time.

 

If you write to a file using (for instance) COPY and want to read it back within the same program, you need to CLOSE the file then re-open it rather than rewinding.

This was for duplicating a paper which had an error in data handling. There weren't 531 data points on the data file and the program used (which was not RATS) rewound the data file to fill the request.
