请教如何用set合并datasets?

shiyiming

有一系列机构相同(data名字最后2位是字母组成的d_xx,而且里面变量完全一样)的data,名字如:d_ac, d_af, d_at, d_be, d_bw,..., d_zp差不多100个左右,现在要简单合并他们.
data all;
set d_ac - d_zp;
run;
但却无法实现,好像必须是连续的数字才能这样合并.需要把ac/af/at/be/bw/.../zp转换成1/2/3.../100或类似的连续性数字,请教高手如何实现,谢谢!

if all like D_xx, you may use this:
data all;
set d_:;
run;

but if some of D_xx you don't want them, you have to set the list all you want.
