macro quoting at macro parameter value

daisy6 — Thu, 05 Oct 2017 16:16:19 GMT

Hello,

When I create a macro parameter procedure, can a macro value be refered?

For example,

%let report=Monthly;
%let infile=monthly_TestReport_2017-9.xlsx;

%ReadXlsbd (inf=&infile., title=&report.);

when I do that, it does not work. Is possible anyway to solve that problem.

Thanks a lot,

Not working? Post log with mprint and symbolgen active. I don't see a reason for not working.

What does 'not work' mean?
Post your full code and log.

Please use MPRINT and SYMBOLGEN to make sure the log has all the macro information.

Basically, this works, so you're doing something wrong but you haven't provided enough information for us to tell you what it is.

%let test=one;
%let random = two;

%macro demo(var=);

%put "Macro Variable is " &var.;

%mend;

%demo(var=&test.);
%demo(var=&random.);

I test my code again, and it works this time.

By any chance are you attempting to use the macro variable Report to place the text "Monthly" into the text of the Infile macro variable?

That would be

%let infile=&report._TestReport_2017-9.xlsx;

It really helps to show what you think you want to build given pieces as we are having to make lots of guesses.

@daisy6

If using SAS EG or SAS Studio then make sure that your final test is done AFTER you've closed and re-opened your SAS session. This is to avoid that some "left-overs" allow you to run code which actually doesn't work in a fresh session.
