Subject:      Need help escaping macros
Content-Type: text/plain; charset=ISO-8859-1

I have some code that sort of like the code below.  When I run this
code, it writes a WARNING to my log file "unresolved symbol W".

    data matt;
        s = "A&W root beer";
        call symput('mattmacro', s);
    run;

    proc print data=matt;
    run;

    data two;
        set matt;
            if s = "&mattmacro" then output; /* source of warning */
    run;

I've been messing around with using %QUOTE, %NRQUOTE, %STR, %NRSTR,
but I'm not making progress.  Either I end up escaping the mattmacro
to the point where data two has zero rows (this is wrong), or I
trigger the warning.

This is the last warning in my program and I want it gone.

Thanks!

Matt
