AUTOSCAN - The ugly history
───────────────────────────
10-19-90 Version 1.0:
First public release, needed a config file to run and only
supported ZIP and ARC files...Needed a dedicated "work" directory
10-20-90 Version 1.1:
Someone wanted the ability to scan the hard drive(s) so that code
was thrown in...(yea - a day later.)
Added built in config file editing.
11-15-90 Version 1.2:
Removed all code for the config file and built in the ability to
search the current path for any needed files. Added support for
ZIP,ARC,ICE,LZH and PAK files..Installed code to make it's own
work directory and delete it when done...NO config file is now
needed..(ok Eric ?? <smirk>).
The log file was placed in the root directory of the current drive,
also added time and date to the log.
12-23-90 Version 1.3:
Made MANY changes is the source code and dropped the size of the
EXE file..Log file is now placed in the same directory as
AUTOSCAN.EXE, beats having a few of them eh?. Extended the scanning
of hard drives to C: thru H:. Log file reports more of what is going
on plus it's easier to read now..
Check for DosExitcode and Doserror installed, made it a little more
reliable when it checks how scan.exe exited.
Installed code to run CHECK.EXE to simulate a Virus...
Happy Christmas!!!!
01-13-91 Version 2.0:
Hmm many changes to the source code. AUTOSCAN will now scan archives
within archives to ANY level and ANY combination of compression types.
Added support for LHARC and PKXARC, AUTOSCAN will use them if ICE.EXE
or PKUNPAK.EXE aren't found. It will also check free disk space, if
the amount of free space is less that 50% times the archive size
AUTOSCAN will exit and make a note in the log.
AUTOSCAN will now keep track of the files it has already processed.
AUTOSCAN, if it detects a bad Archive or Virus, will rename the file
with and extension of .BAD.
Fixed a minor problem that if any needed file wasn't within the first
40 characters of the path it wouldn't be found..oops..sorry..
Added in several Dos Errorlevels so batch files can be used effectivly.
'Bout it for now I think ! Any Ideas ?
First version released onto the SDS Network..
01-27-91 version 2.1:
Hmm many changes to this one too, just when I thought I was done..
Thanks to a few people around the country I have added a few more
things in....
Added F10 to abort - Please read the docs. reguarding this option.
Added /N and /A these option are for the registered version ($10) and
allow AUTOSCAN to check for Bad Archives only and Scan all drives
and examine ALL ARCHIVES...WOW!.
MANY internal changes to the code, streamlined a few of the procedures
and functions...Changed the amount of memory that Autoscan needs in
order to prevent runtime errors on some machines.
Scan.Exe will now only scan RAM on the first pass, thus the runtime of
autoScan is vastly reduced. Remember AUTOSCAN ? for online Help.
GO GIANTS!!!!..
03-06-91 Version 3.0 Beta and 3.0
I don't know where to start describing what I have been doing to this
program..Almost all of the internal code got 'tweaked' by the use of
Turbo Profiler (great program to show where time is spent in a prog.)
Added the Reboot option /F, the config file support and switch /K.
The most important feature now is that AutoScan no longer looks at the
file extension to determine the archive, it now examines the header of
each file to determine if it is an archive and if so what type..Made
things more reliable and a lot faster...Fixed a minor bug with the /O
option, you can now specify a path and filename. Reworked AutoScan ?
and added some nice artwork (Thanks again to Josh Linder).. Fixed
another minor prob. with the freespace checking, it now reports the
correct size..
OK so whats next ? dunno any ideas ??
03-29-91 Version 3.1
Reduced the amount of Stack space used and added command line parameters
for SCAN.EXE from within the config file. The tampering and self virus
checking has been greatly improved. AutoScan will check its file size,
time stamp and it's CRC. If any of these fail AutoScan will NOT run.
06-08-91 Version 3.2
Included the /U option to specify the "unarchive drive". Rewrote some
internal routines to increase AutoScans speed and lower the exe size.
Rewrote the errorhandler routine to display two error codes to help
track down any problems (Problems???? naaa).. See ERROR.LST for details
Some DOS version do not report the drive name where AutoScan resides,
added the Environment Variable AUTOSCAN - See the docs on this one...
Made a few cosmetic changes here and there... Got rid of the nasty
flashing unregistered delay bit (whew)..
06-23-91 Version 3.3ß
Added support for LHA.
Rewrote FINDWORKDIR, GETDRIVE to include all drives A thru Z.
/U and /S also expanded to drives C thru Z...NOT YET RELEASED
(as of 08/16/91).
Lotta tweaking!
Changed the FILEMODE when examining an archive just in case the file
had the READ ONLY bit set.
