以上这样输入数据是可以的~~~
但是下面这种方式：

proc sql;
create table newtable (region char(8),state char(2),month num informat=monyy5. format=monyy5.,
headcnt num,expenses num,revenue num);
quit;

*用VALUES子句插入行;
proc sql;
insert into newtable
values ('EASTERN','VA',FEB78,10,7800,15500)
values ('PLAINS','NM',MAR78,2,1350,500);
select region,state,month,revenue from newtable;
quit;

values子句报错，FEB78格式不对，还试过'FEB78'，'FEB78'd都不对，那么此时要显示FEB78在values里面该如何写呢？？各位大侠多多指教~~~
