There exists already a program that will check the Workbench items that are
not likely to be changed by the user - the C: commands, the libraries, the
devices and handlers.  Jim Butterfield, well-known for nifty utilities for
Commodore computers since l978, wrote a program called SysCheck as an aid
in moving things over to 1.3.  He uses both the size of the program and its
checksum in culling out the items on a disk that are not the release version of 1.3.  It now turns out that SysCheck also makes a dandy program for
checking out the workbench against the IRQ virus.

SysCheck is available on CIS, AmigaTech Forum, and is on many bulletin
boards as well.  It is well worth the effort it takes to download.
