Using RFIND produces exactly the same results as using FIND without a search argument.
If no previous FIND existed, the RFIND command ends in error.
If the string was found on a line or in a column that was not previously in view, the display is scrolled just enough to display the string.
If the previous search reached the top or bottom of the file without successfully locating the search argument, a repeat FIND command starts searching from the other end of the display, but always in the same direction as the previous search.
Searching for non-displayable data is not supported.
