st: adding quotes to a macro or variable

[Laura Gibbons <gibbonsl@u.washington.edu>]

Is there any way I could change a macro value from xxx to "xxx".

.local l="xxx"
.di "`l'"
xxx

I want the macro to actually be "xxx", including the quotes.  I've tried 
adding them around with no success, and things like

. local l="xxx"

. local l='"`l'"'
'"xxx"' invalid name
r(198);

But as you can see I'm in need of help.  I'm in version 10 on Windows XP.

thanks- Laura
