Item 62 of 63 Mark item for review  

  Given the following macro program      

  and invocation:

  %macro MAKEPGM(NEWNAME, SETNAME);      

     data &NEWNAME;     

        set &SETNAME;   

     run;     

     %put ---> inside macro &NEWNAME &SETNAME;

  %mend;      

  %MAKEPGM(WORK.NEW, SASHELP.CLASS)      

  %put ---> outside macro &NEWNAME &SETNAME;   

Which of these choices shows the correct %PUT  

statement output if the program is submitted at

the beginning of a new SAS session? Note that  

other lines may be written to the SAS log by the  

program but only the %PUT output is shown here.

        A.

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

---> outside invocation WORK.NEW SASHELP.CLASS      

     B.

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

---> outside invocation &NEWNAME &SETNAME

     C.

---> inside macro &NEWNAME &SETNAME

---> outside invocation WORK.NEW SASHELP.CLASS      

     D.

---> inside macro &NEWNAME &SETNAME

---> outside invocation &NEWNAME &SETNAME

答案是B，但是我的疑问是答案为什么不是？

---> inside macro SASHELP.CLASS SASHELP.CLASS
