Wierd... This shouldn't happen. Does your shell have an
internal "expr" command that acts strangely?

Maybe the shell doesn't know the variable substitution
"${FOO##*bar}" which removes the longest prefix ending
with "bar".

What happens if you enter this:

	$ FOO=`grep "APS.*_BEGIN" /etc/printcap | sort -n`
	$ echo $FOO
	$ echo ${FOO##*printer}

Maybe your printcap file is messed up. Each printer
definition should start with a line similar to

# APS42_BEGIN:printer42

with no other characters after the last number.
