%macro MAKEPGM(NEWNAME, SETNAME);
data &NEWNAME;
set &SETNAME;
run;
%put ---> inside macro &NEWNAME &SETNAME;
%mend;

%MAKEPGM(WORK.NEW, CLASS)
%put ---> outside macro &NEWNAME &SETNAME;

A. ---> inside macro WORK.NEW SASHELP.CLASS

对不起，answer给错了。为什么第二个put语句没能给出&NEWNAME &SETNAME 的值？

%macro MAKEPGM(NEWNAME, SETNAME);
   data &NEWNAME;
      set &SETNAME;
   run;
   %put ---> inside macro &NEWNAME &SETNAME;
  %mend;

  %MAKEPGM(WORK.NEW, CLASS)
  %put ---> outside macro &NEWNAME &SETNAME;

B. ---> inside macro WORK.NEW CLASS
  ---> outside invocation &NEWNAME &SETNAME
