Macro 变量调用问题

shiyiming

data _null_;
        x='the answer is "yes"';
        call symputx('test',%nrstr(x));
run;
ods listing close;
ods noresults;
ods tagsets.excelxp
file="c:/test.xls"
style=meadow
options (
sheet_name = "test");
title1 "purpose:  &test";

proc print data=tmp; run;

运行上面的程序会有错误，应该怎么修改呢？

[code:1b40f9xf]data _null_;

call symputx('test',x);
run;
ods listing close;
ods noresults;
ods tagsets.excelxp
file="c:/test.xls"
style=meadow
options (
sheet_name = "test");
title1 "purpose: %superq(test)";

proc print data=tmp; run;[/code:1b40f9xf]

title1 "purpose: %superq(test)";

proc print data=tmp; run;[/code:22v9j3m9][/quote:22v9j3m9]


后来用%bquote解决了
%superq  和 %bquote 有什么区别呢？
