Hello team, %let x=1; %let items=2; %macro test(val); data _null_; call symputx('items', ' leading and trailing blanks removed ', 'L'); call symputx(' x ', 123.456); run; %put local items &items; %mend test; %test(100) %put items=!&items!; %put x=!&x!; Can someone please explain about this?   call symputx('items', ' leading and trailing blanks removed ', 'L'); What does this three strings passed to symputx mean? I look at the log, I am totally confused.    First, it says these two macro variables: %let x=1; %let items=2;   and then it says: call symputx('items', ' leading and trailing blanks removed ', 'L'); call symputx(' x ', 123.456);   what does %test(100)?
