I've recently observed a difference between ksh and sh.  The ksh is the
one on the UNIX-PC.  The following script works correctly with all bourne
shells I've found, but fails on that ksh:

if [ -w foo -r foo ] ; then
	echo file foo is readable and writable
else
	echo file foo is not readable and writable
fi

On ksh I get a syntax error.  Changing the first line to
	if [ -w foo -a -r foo ] ; then
causes it to work correctly on all systems.
