SPAWN 1.3 is used to SPAWN (shell out to, exec a) CHILD program.
This program has no practical use, as is. It is just a teaching
example.  It also acts as a skeleton you can cannibalize from to
create your own real-life programs.  I have left out the
analysis of child failure.  OPTASM/MASM source included.  This
program is copyrighted but may be used freely for any purpose
except military.  Version 1.3 just displays the new address and
phone number.  You might be interested in the more elaborate
version of this program called SHELL.  SPAWN stays resident
where SHELL rolls itself out to disk before spawinng.
