Herb.

	There is no way to directly retrieve the return code for a MSDOS
program which you shell from VB.  The best you can do is shell to a batch
file which, in turn, runs your MSDOS executable.  The batch file can then
detect the errorlevel of your MSDOS program and redirect it to a temporary
text file.  You can then read the value from that file into your VB program.

	Your second question (about waiting for a task to complete) is
much tougher, and the document we are sending out to you should answer it.
