SCROLLBK - DOS Screen Scroll Back Utility
_____________________________________________________________________


DESCRIPTION

  SCROLLBK allows you to capture screen information that has rolled
  off the top of your screen and buffers it into a conventional or
  expanded memory buffer.  At any time you can then press the SCROLL
  LOCK key on your keyboard and scroll back through the previous
  screens.  SCROLLBK supports MDA, HERCULES, CGA, EGA and VGA video
  cards.  It supports all text modes that use 80 columns.


VERSION

  2.30  08/18/91


RESIDENT MEMORY REQUIREMENT

  2,688 bytes


COMMAND FORMAT

  SCROLLBK /Mnnnn [/EMS][/D][/C][/?][+][-][/U][/Ffname][/A][/O]

  /Mnnnn   This tells SCROLLBK how much memory to use in nnnn k bytes
           for the scroll back buffer.  Conventional memory will be
           used unless you specify the /EMS parameter described below.
           The resident memory usage will be the 2k for overhead + the
           buffer size unless EMS is used.

  /EMS     Use Expanded Memory for Buffer Space.  The amount of memory
           buffer specified by the /Mnnnn parameter will be used out
           of EMS rather than conventional memory.  EMS 3.2 or 4.0 is
           supported.  The amount of memory in K bytes specified in
           the /M parameter will be rounded up to the nearest EMS page
           (16k).

  /NOH     Suppresses the Header display.

  /D       Some video BIOSes have a built in scroll back buffer and
           will cause the SCROLLBK buffer to have a duplicate of every
           line that has been displayed.  Using this parameter should
           compensate for the built in buffer and eliminate the double
           lines.  Compaq EGA and Orchid VGA cards are known to have
           this problem.

  /C       This option will clean out the buffer so that it starts
           recording with a clean memory from this point on.

  +        Enable SCROLLBK.  This turns on the SCROLLBK functions if
           previously disabled.

  -        Disable SCROLLBK.  This leaves the program in memory but
           turns off the capture and display features.

  /U       Uninstall SCROLLBK.  Removes the program from memory if
           possible.

  /Ffname  Will save the current contents of the scroll back buffer to
           a file named fname.

  /A       If the /F parameter is used and a file already exists with
           the same name, this parameter tells SCROLLBK to append the
           current buffer onto the existing file.

  /O       If the /F parameter is used and a file already exists with
           the same name, this parameter tells SCROLLBK to overwrite
           the existing file with the current buffer information.



VIEWING BUFFER

  [SCROLL LOCK]  Activates the SCROLLBK viewing feature.  Disables the
                 cursor and allows the keystrokes listed below to take
                 effect. Will stay in the viewing mode until [SCROLL
                 LOCK] is pressed again, which will deactivate the
                 viewing mode.  Pressing [ESC] will also exit the
                 buffer viewing mode.

  [UP ARROW]     Move up the viewing one line

  [DOWN ARROW]   Move down the viewing one line.

  [PGUP]         Move up in the buffer viewing one Screen

  [PGDN]         Move down the buffer on screen.

  [HOME]         Go to the top of the buffer

  [END]          Go to the bottom of the buffer
