Code is not working as intended

[atinytale]

%let x= 2020Q1;

%let y= 0;

%macro xyz();

%if &y =0 %then 

%let abc = %sysfunc(intnx(qtr, %sysfunc(inputn(&x, yyq6.)),0,b),yyq6.);

%mend;

%xyz;

when I execute the above code, the macro abc is not resolved. Can anyone please help?

thanks in advance.

If you want to use macro variable abc outside of macro, you need to make it a global macro variable:

%let x= 2020Q1;
%let y= 0;

%macro xyz();
%global abc;
%if &y =0 %then 
%let abc = %sysfunc(intnx(qtr, %sysfunc(inputn(&x, yyq6.)),0,b),yyq6.);
%mend;

%xyz;
%put &=abc;

ABC=2020Q1
