-Once a 16-bit DOS application has read standard input from a console and 
-then quit, all subsequently run 16-bit DOS applications will see the 
-standard input as already closed.  32-bit applications do not have this
-problem and will run correctly, even after a 16-bit DOS application thinks

-Redirection between the \fBNUL:\fR device and a 16-bit application does not
-always work.  When redirecting from \fBNUL:\fR, some applications may hang,
-others will get an infinite stream of

-bytes, and some will actually
-correctly get an immediate end-of-file; the behavior seems to depend upon 
-something compiled into the application itself.  When redirecting greater than

-All DOS 16-bit applications are run synchronously.  All standard input from
-a pipe to a 16-bit DOS application is collected into a temporary file; the
-other end of the pipe must be closed before the 16-bit DOS application
-begins executing.  All standard output or error from a 16-bit DOS
-application to a pipe is collected into temporary files; the application
-must terminate before the temporary files are redirected to the next stage
-of the pipeline.  This is due to a workaround for a Windows 95 bug in the
-implementation of pipes, and is how the standard Windows 95 DOS shell
-handles pipes itself.

-Certain applications, such as \fBcommand.com\fR, should not be executed
