/* Virus_Checker7 for Directory Opus 5 and Virus_Checker 7.
By Leo Davidson ("Nudel", Pot-Noodle/Gods'Gift Utilities)
$VER: Virus_Checker7 1.2 (18.8.95)
NOTE: This script _requires_ DOpus v5.11 or above.
If you include the path of a file/dir on the command line, using a {}, only
this file/dir will be tested. If you omit the {}, the program will check
all selected files and directories in the SOURCE lister for viruses.
If Virus_Checker's ARexx port is not found, the program will be run for
you (you should edit the path below). This means the script may fail if
you give an incorrect path to the Virus_Checker program.
If the Virus_Checker's ARexx port takes over a minute to appear, an error
requester will appear on the DOpus screen and the script will quit.
If Virus_Checker was running to start with, it will be left running after
the script has completed. Otherwise, it will be removed from memory.
When a virus is detected a beep will sound and once all files have been
checked you will get a requester with a list of infected files (including
the type of virus). It is possible that the requester will fail to
appear if it becomes too large to fit on the screen. The script will
detect when this happens and output the results to a shell window instead.
Thanks to John Veldthuis <johnv@tower.actrix.gen.nz> for writting
Virus_Checker, allowing me access to the VC7 beta versions, and for giving
me a virus-infected file (!) to test this script with.
For a "check selected files for viruses" function, call as:
------------------------------------------------------------------------------
ARexx DOpus5:ARexx/Virus_Checker7.dopus5 {Qp} {Ql}
------------------------------------------------------------------------------
Turn off all switches.
For an "Un-LhA to a directory and check for viruses" function, call as:
------------------------------------------------------------------------------
AmigaDOS C:LHA -M x {fu} {d}{ou-}/
ARexx DOpus5:ARexx/Virus_Checker7.dopus5 {Qp} {Ql} {d}{o-}
------------------------------------------------------------------------------
Switches: Do all files

v1.00 -> v1.01 - Some minor tidying up.
Now checks to make sure the DOPUS.x port exists.
v1.02 -> v1.3 - Now uses Show() instead of ShowList(). (Thanks Stoebi)
Style Guide compliant version numbering and $VER string.
