Subject: SCAN -- a program to look at text and squeezed files

                        SCAN Version 1.00

SCAN, based on the program BISHOW, is a program to view text and 
squeezed text files.   It can be used to take quick looks at files 
without unsqueezing them or loading a large text editor, or to 
examine another file with the RUN command while in Wordstar. 
You can display the file in either direction, search for
strings, or view only selected columns of the file.  In function, it
is identical to BISHOW Version 1.11 with two major additions  the
search function, and the ability to bishow a squeezed file.  The
program is written for Z80's only, and the addition of the unsqueezing
routines has ballooned the program to just under 4K.  The various
commands for SCAN are:

     1)   Display the Next Page (Forward a Page) 
     2)   Display the Previous Page (Back a Page)
     3)   Display the Next Line (Next Line)
     4)   Display the Previous Line (Back a Line)
     5)   Display the First Page (Top of File)
     6)   Display the Last Page (End of File)
     7)   Quit (End SCAN)
     8)   Set Screen Parameters
     9)   Search for a String of Characters
          Searching includes wild card characters, forward and
          backward search, and option to ignore upper/lower case.
    10)   Display Help

As distributed, SCAN contains a small patch file (SCANPAT.ASM). 
This allow changing the various default parameters, as well as 
the commands and terminal characteristics.  Look at this file for 
information about modifying SCAN.  The distributed version of 
SCAN is configured for the standard command names and a "plain 
vanilla" CRT.  This should work for most terminals.

If you are interested in the program, please E-mail me a message.
If there is enough interest, I will distribute it via net.sources,
otherwise I'll E-mail it back to you.  The normal distribution package
includes SCAN.DOC, SCANPAT.ASM, AND SCAN.HEX.  The sources is written
in Zilog mnemonics and is not being distributed at this time.
