Using this command line switch eliminates
shared memory corruption problems. However, this feature comes at the cost of performance
and overall system resource usage. Unlike 32-bit memory spaces, 16-bit memory spaces remain
fixed in memory, which uses the memory inefficiently and causes memory fragmentation.
Memory fragmentation can cause Windows to perform inefficiently, leading to performance
problems. In short, use this command line switch only when you actually experience problems.
/SHARED Starts the 16-bit Windows application in a shared memory space. This is the default
setting and you should normally use it unless you experience memory corruption problems
while running the application.
/LOW Starts the application in the IDLE priority class. Use this priority setting for applications
that only run when other applications don??™t require the processor. This command line switch
helps the system function more efficiently when you want to run the application as a background
task and don??™t care when it completes its work.
/BELOWNORMAL Starts the application in the BELOWNORMAL priority class. Use this priority
setting for background applications that you want to complete in a timely manner, but not at the
expense of foreground applications.
