%macro one(input);
%two;
%mend;
%macro two;
data _null_;
call symputx ('date','12SEP2008','L');
run;
%put the value is &date;
%mend;
%let date=31DEC1006;
%one(&date)
What is the result when the %put statement executes?
答案是12SEP2008 retrieved from the local symbol table for the TWO macro.
我在网上查了call symputx routine的用法，关于L的解释是：
L specifies that the macro variable is stored in the most local symbol
table that exists, which might be the global symbol table. | s*******2
