Macro variable is declared using %str function, but output is not fetching?

Hi All,

I am try to declare a macro variable and print the macro variable in log window using the put statement, but output is not fetching. Can you help me.

Attaching the output image for reference.

Code:

%let pass=%str(rAk%B25%);
%put &pass;

Thanks.

Result:

Do you actually have the %B25 macro that you are trying to call? What does it do?

Perhaps you meant to use %NRSTR()? if so double the % characters to mask them.

1    %let pass=%nrstr(rAk%%B25%%);
2    %put &pass;
rAk%B25%

Your code it probably still looking for the closing ), right parenthesis, since you masked the one in the first line by prefixing it with a % character.

1    %let pass=%str(rAk%B25%);
2    %put &pass;
3    );
WARNING: Apparent invocation of macro B25 not resolved.
ERROR: Open code statement recursion detected.

Add the closing ) to your %LET.

1    %let pass=%str(rAk%B25%));

2    %put &pass;

rAk%B25)

The macro tokens like % complicate things a bit. %superq should help.

data _null_;
  call symput('pass','rAk%B25%');
run;
%put %%SUPERQ(pass);
