   SCAN is a bi-directional video-oriented text file display utility that uses
the basic WordStar command  set to  control  viewing of normal text  files and 
library member files in both ZCPR3 and CP/M environments.   

   SCAN allocates all available memory up to  the CCP or lowest  RSX  for text
buffers and  uses a  dynamic  buffer  allocation  process  to  allow  full bi-
directional browsing through text files of any size.   The  size of  the  file
being viewed is not limited by available memory space.  Files may be viewed as
straight text files or WordStar and ZCPR3  video display modes  are available.
See SCAN.HLP for more details on the features and capabilities of SCAN.

 SCAN Notes - 1/2 

   a. Vs 2.3 updates (9/12/90, Terry Hazen):
      - improved command buffer
      - locates CCP by first checking for a ZCPR3 extended environment.   This
        properly locates the CCP address, and the end of the SCAN text buffer,
        so as to avoid inadvertently overwriting a non CP/M-standard CCP.   If 
        no extended environment is found,  the  CCP location is inferred as in 
        previous versions.
      - command help screen has been  rewritten to  show the alternate single-
        character commands  instead of the  default  WordStar commands,  which 
        should already be familiar to the user.  
      - help screen now automatically reflects the patchable  single-character 
        commands contained in the patch section of the command table.
 SCAN Notes - 2/2 

   b. Vs 2.2 updates (5/18/90, Terry Hazen):
      - Changed find string routine so  entire  screen isn't scrolled to  mark
        next find when next find is still on current screen.  
      - Added mark and find place markers 0-9.  
      - Added command  buffer that  speeds  up  multiple command  sequences by 
        interrupting current display operation if more commands are pending.  
      - Fixed error that loaded wrong environmental processor speed value.
      - Added additional ^QQ exit command.  
      - Many general code revisions.
