SAS User File for HC001 Data     

This file contains information and sample SAS programs to create a permanent
SAS dataset, for users who want to use SAS in processing the MEPS data
provided in this PUF release.

A.  A Sample SAS Program for Converting the ASCII Data File to a Permanent
SAS Dataset

The complete SAS statements (INPUT and LABEL) included below are
intended to save time for those users wishing to create a permanent SAS
dataset from the HC001.DAT ASCII data file.  These statements must be used     
in combination with other SAS statements to create the appropriate SAS
program, as shown below.  To use the statements provided to create a SAS
program, you will need an ASCII text editor.  If you are using an interactive
form of SAS (Windows, UNIX, OS2, etc.), use the editor provided as part of the
SAS software. 
  
Following is a sample SAS program that will convert the ASCII data file to SAS
format.

     LIBNAME PUFLIB 'C:\MEPS';
     FILENAME IN1 'C:\MEPS\HC001.DAT';     

     DATA PUFLIB.HC001;     
     INFILE IN1 LRECL= 264;   
     INPUT .....; * to user: insert the complete INPUT statement that is
provided in Section C below;
     LABEL .....; * to user: insert the complete LABEL statement that is
provided in Section C below;
     RUN;

Here is an explanation of the SAS statements used in the program above.

LIBNAME statement: This tells SAS the location (directory name) of the
permanent SAS dataset.

FILENAME statement: This tells SAS the location of the input ASCII data file.

DATA statement: This signifies the beginning of a SAS DATA step and specifies
describes the output SAS dataset, referencing the LIBNAME entry (PUFLIB) and
assigning an internal SAS dataset name (HC001).  In the example, after the     
successful completion of the DATA step, a PC file named HC001.SD2 would have   
been created in the C:\MEPS directory.

INFILE statement: This tells SAS the location (directory and file name) of the
input ASCII data file.  Also provided is the logical record length (264
bytes), with the default of RECFM=V implied when this parameter is omitted. 
LRECL and RECFM are optional parameters in the INFILE statement.  With regard
to these options, please note the following: the ASCII data file HC001.DAT     
contains a 2-byte carriage return/line feed at the end of each record.  When
converting to a PC-SAS file, the LRECL option should be used to specify the
record length to avoid use of a default record length by PC-SAS.  If the
RECFM=V option is used, the LRECL option must be specified as the logical
record length (e.g., 264 for HC001.DAT).  If RECFM=F is used, then the        
LRECL value must  be specified as the logical record length plus 2 (266 for   
HC001.DAT).  Note that if the RECFM option is omitted, then the default     
option of RECFM=V is automatically used, and LRECL should be specified as the
logical record (264 for HC001.DAT).        

INPUT statement: This specifies the input record layout, giving names and the
beginning and ending column positions for data items (which become SAS
variables) in the ASCII data file (HC001.DAT).  Variable type (numeric or     
character) is also defined via the INPUT statement.

LABEL statement: This associates descriptive names with the SAS variables.

RUN statement: This tells SAS to execute all commands up to this point.


B.     Optional Format-related SAS Statements

If a user wants to use formats for the SAS variables, a SAS format library
must first be created.  Below is a SAS program that will accomplish this.

     LIBNAME PUFLIB 'C:\MEPS';
     
     PROC FORMAT LIBRARY=PUFLIB;
     VALUE .....; * to user: insert the complete set of VALUE statements found
in Section C;
     VALUE .....;
     .......... ;
     RUN;


Below is an example of how to use the SAS formats defined by the PROC FORMAT
procedure.

     LIBNAME PUFLIB 'C:\MEPS';
     OPTIONS FMTSEARCH=(PUFLIB); 
   
     PROC FREQ DATA=PUFLIB.HC001;     
     TABLES .... / LIST MISSING;
     FORMAT varnam1 fmtnam1.  Varnam2 fmtnam2.  .... ;
     * to user: substitute varnami and fmtnami with actual variable names and
format names;
     *     Insert the FORMAT statement provided in Section B, if you are using
all the variables;
     *     in the TABLES statement;
     TITLE "Frequency Distributions ....";
     RUN; 

Here is an explanation of the SAS statements used above.

LIBNAME statement: This tells SAS the location (directory name) of the SAS
format library.  Please note that SAS datasets (file name extension is 'SD2')
and format libraries (file name extension is 'SC2') can be stored under the
same directory.

OPTIONS FMTSEARCH=...: This specifies the SAS format library.

PROC FORMAT statement: This identifies the SAS procedure that will make SAS
formats according to VALUE statements.  Formats will be stored in a file named
FORMATS.SC2.  Please note that the option 'LIBRARY=...' can be omitted, if the
user does not want to create a permanent SAS format library.  When simply
'PROC FORMAT;' is used, the formats are defined only for the duration of the
batch SAS program or an interactive SAS session.

VALUE statement: This gives a) names to formats; and b) descriptive labels for
individual values, or range of values.  The format names can then be invoked
using a FORMAT statement, if desired.

PROC FREQ statement: This identifies the SAS procedure that will generate
frequency distributions of variables specified in the TABLES statement,
formatted if a FORMAT statement is used.  The input SAS dataset is specified
in the 'DATA=' option.

FORMAT statement: This associates existing formats with variables.  When using
this statement, the formats must have already been created with a PROC FORMAT
procedure. 

RUN statement: This tells SAS to execute all commands up to this point.


NOTES:

     1)  Use of formats is entirely optional, and depends on the type
     of analyses that you are doing.  It is recommended that you create
     and use them as appropriate.

     2)  The names used in the LIBNAME and FILENAME statements shown
     above (i.e., PUFLIB, IN1) are arbitrary; they are only temporary
     aliases.

     3)  You only create the permanent SAS data set once.  Additional
     analyses can be run using this permanent dataset.

     4)  The file and directory specifications in the LIBNAME and
     FILENAME statements are Windows syntax and may need to be modified
     for other operating systems such as UNIX, MAC/OS, VMS, or OS/2.
