***********************************************************************
A note to SAS users
***********************************************************************

The SAS data file is provided in the format used for SAS versions 6.08
through 6.12, in order to increase the accessibility of the file to
users who may not have the most recent versions. Generally it is best
not to mix multiple versions of SAS files in the same directory. For
those users with more recent versions of SAS, it would be best to use
SAS to first read the file from the CD-ROM (or some location where it
has been copied), and then save it in another directory. (SAS will
automatically save it in the appropriate version if there are no older
versions of SAS files in that directory.)

The SAS data set has user-defined value-label formats. These are
provided in the fmtlin.sd2 data set. The following code can be used
to convert the SAS format file to a SAS format catalog.

libname library "path" ; /* the path to the above SAS data sets */
proc format library=library cntlin=library.fmtlin fmtlib ;
run ;

For example, if the data sets are in a library called
"c:\ssocs" then the code might say:

libname ssocs "c:\ssocs";
proc format library=ssocs cntlin=ssocs.fmtlin fmtlib ;
run ;

As another example, in order to save the format catalog using
a more recent version of SAS, the following code could be used:

libname in "c:\ssocs";
libname out "c:\ssocs2000";

proc format library=out cntlin=in.cntlin fmtlib ;
run

***********************************************************************
Reading the ASCII (text) fixed format data file
***********************************************************************

This disk contains a SAS program and a SPSS program to read the ASCII
(text) fixed format data file (ssocs-ff.txt).

To use the SAS program (PUB.sas), you must specify the correct path to the
ASCII (text) fixed format data file (ssocs-ff.txt).

The default location specified in the program is c:\ssocs.  To specify the
a different location for ssocs-ff.txt modify the following macro variable statement:

%let path = c:\ssocs ;

For example, if you have copied ssocs-ff.txt to c:\Projects, then make this change to
the macro variable:

%let path = c:\Projects ;

Similarly, to use the SPSS program (PUB.sps), you must specify the correct path to
the ASCII (text) fixed format data file (ssocs-ff.txt).

The default location specified in the program is C:\WINDOWS\DESKTOP\.  To specify the
a different location for ssocs-ff.txt modify the following statement:

/FILE = 'C:\WINDOWS\DESKTOP\SSOCS-ff.txt'

For example, if you have copied ssocs-ff.txt to c:\Projects, then make this change to
the statement:

/FILE = 'C:\projects\SSOCS-ff.txt'
