Thank you, Tom. Now I am much clearer about these macro functions. Really appreciate.
Why your attempt doesn't work:
When you have this
proc print data=admit; where name in ("&name"); run;
And name is
Murry. W, Almers. C
Then the Proc print resolves to
proc print data=admit; where name in ("Murry. W, Almers. C"); run;
Which is not the same as the code that executes because each separate value in the IN comparison needs to be separately quoted.
Yes, you are right, ballardw. Actually I realized this point, but I don't know how to correct it, I mean how to use a macro to solve this problem. Now I got ideas from this post, thanks.
