Does %superq work with a construct like &&x&i ?

PaigeMiller — Mon, 09 Sep 2013 17:57:26 GMT

I have many macro variables, &x1, &x2, &x3 ... containing text strings. I loop through all of them, using &&x&i to refer to each variable.

In one or more of the text strings, there might a percent sign or ampersand, for example the text string assigned to &x3 is: Image_Test BfCent_AB (%rms) 114

I want to use the %superq so that SAS will not resolve the apparent macro referece %rms in the text strign.

I'd like to use something like %superq(&&x&i) in my loop, but of course that won't work within %superq. Is there a modification or workaround that would allow this to work?

I have tried %nrbquote(&&x&i) and that appears to work, but I get a worrisome WARNING in the SASLog that says:

Apparent invocation of macro RMS not resolved.

Try this %superQ(X&i)

With SUPERQ you "point" the location of the data you want quote. With NRBQUOTE you quote the resolved value of a macro variable reference. Or something like that.

Yes, that works. It's one of those "why didn't I think of that" moments. Thanks again, data _null_
