REVIEW [bytesize|-C|-Sfilename]

With the reviewbuffer you can see that again what scrolled out of the
window or was  redirected . In the reviewbuffer are all outputs stored.
To see what is in the reviewbuffer just press SHIFT TAB. This activates
the  MORE  text reader.
* "REVIEW bytesize" (re)creates a reviewbuffer with the given size.
* "REVIEW 0" removes the reviewbuffer.
* "REVIEW" without arguments shows the adress and size of the current
  reviewbuffer.
* "REVIEW -C" clears the reviewbuffer.
* "REVIEW -S filename" saves the reviewbuffer to that file.

eg.     review 10000        {starts normal reviewbuffer}
        review 50000        {starts big reviewbuffer}
        review 0            {deletes reviewbuffer}

NOTE 1: Because it uses a circular buffer with fixed size, this is much
  faster than having a fixed number of lines. The decrease in scrolling
  speed is neglible.
NOTE 2: The Write function of the dos.library will be patched, so
  there might be problems with other programms that patch this too.
