   Recreating a SAS Data Set from a Compressed SAS Transport File
For SAS transport file created by PROC CPORT, follow these steps to recreate the SAS dataset:

Begin by uncompressing the downloaded file. Use unzip if you are unzipping the file on an Unix machine or use WinZip/pkzip if you are unzipping the file on a PC. You will then have the SAS Transport file created using PROC CPORT.

The program listed below will recreate the SAS data set from the Transport file. WARNING: All of the SCF data sets are rather large, make sure you have enough space to recreate the data set before running the program.
LIBNAME OUT 'output SAS library';
FILENAME IN 'input transport file name';

PROC CIMPORT DATA=OUT.dataset INFILE=IN;
RUN;

For SAS transport file created by PROC COPY with an XPORT option, follow these steps to recreate the SAS dataset:

Begin by uncompressing the downloaded file. Use unzip if you are unzipping the file on an Unix machine or use WinZip/pkzip if you are unzipping the file on a PC. You will then have the SAS Transport file created using PROC COPY with an XPORT option.

The program listed below will recreate the SAS data set from the Transport file. WARNING: All of the SCF data sets are rather large, make sure you have enough space to recreate the data set before running the program.
LIBNAME NEW 'output SAS library';
LIBNAME TRANS XPORT 'input transport file name';

PROC COPY IN=TRANS OUT=NEW;
RUN;

ENDSAS;

我有个数据文件，用sas不能直接打开，说是要用上述方法导入，但我不太明白具体步骤和顺序。请大家帮助，谢谢！

这两个是一起用，顺序是怎样的。

Your variable "AGECL" should be class variable instead of analysis variable.

Based on your data, i tried this:

data empiricalnew;
 input INCOME NETWORTH AGECL;
 cards;
1304132.14 5529000 3
1304132.14 6379000 3
1304132.14 6520000 3
1304132.14 6480000 3

   proc means data=empiricalnew noprint;
        by AGECL;
        var income NETWORTH  ;
        output out=final(drop=_type_ _freq_) mean=IncomeMean NETWORTHmean ;
   run;
   data thesis.finalnew;
       set thesis.final;
    if AGECL= 1 then age1=1;else age1=0;
       if AGECL= 2 then age2=1;else age2=0;
    if AGECL= 3 then age3=1;else age3=0;
    if AGECL= 4 then age4=1;else age4=0;
    if AGECL= 5 then age5=1;else age5=0;
    if AGECL= 6 then age6=1;else age6=0;
   run;

What is LZ's question?

不知道怎样通过这两个过程将一个sas压缩数据文件读入sas

To uncompress a SAS dataset, just use option compress=no in data step. Please see http://www.ciser.cornell.edu/FAQ/SAS/new_compress.shtml and http://www.sfu.ca/sasdoc/sashtml/lgref/z1288760.htm.

In addition, the reference provides the following information (http://www.ats.ucla.edu/stat/sas/library/nesug00/ad1007.pdf) -
As mentioned earlier, each time the SAS System reads (e.g., applies a Procedure or another Data Step) to a compressed data set, the data set must be uncompressed. Users have no control over whether or not the data set is uncompressed; the SAS System does this automatically. Additional CPU resources are required to uncompress the data set before it can be used again by the SAS System.

lz最后怎么导进去的啊，这个文件就没有后缀名是怎么回事
