我有很多SAS DATA 文件，dat1, dat2.... 这些文件结构相同。现在需要把这些文件转
换合并成一个SAS DATASET。最简单的方法就是：
data alldata;
set dat1 dat2.....;
run;
但是文件太多了， 我现在用一个文件（filenames）去记录所有文件名：
names |

pull in an external file. Please refer to the Little SAS book for
fundamental concepts. |

Assume all your datasets are already in working directory, and "filenames"
is a .txt file.
data names;
infile "XXXX\XXXX\filenames";
input name $;
run;
proc sql noprint;
select name into: names seperatedby " "
from names;
quit;
data alldata;
set &names;
run;
There's a limit for the length of macro variable. So if your file names are
too long or you have more than several thousands files you will have to use
more than one macro variable to hold the names. |

以。 |

You can always refer to the SAS online doc http://support.sas.com/onlinedoc/913/docMainpage.jsp, and the SUG/PharmaSUG papers.
