there should be a way to echo with quotes or escaping

[Dave Yost <Dave@xxxxxxxx>]

Z% echo "abc def"
abc def
Z% echoquoted "abc def"
'abc def'
Z% echoescaped "abc def"
abc\ def
Z%

or some such

If there is such a feature, I didn't see it mentioned under the echo 
command in the man page.

Thanks

Dave
