做个宏变量。

感谢回复，我是想用在数组中，所以没考虑宏变量

You will need to query a list of the variables to generate the list of those that you need to drop.

proc contents data=have out=contents(keep=name) noprint ; run;

proc sql noprint ;

select name into :droplist separated by ' '

from contents

where upcase(name) like '%^b' escape '^'

;

quit;

data want ;

  set have (drop=&droplist);

run;
