The MPS-Format SAS Data Set

Example 17.4 Using the %MPS2SASD Macro

We illustrate the use of the %MPS2SASD macro in this example, assuming the files example_fix.mps and example_free.mps are in your current SAS working directory.

The MPS2SASD macro function has one required parameter, MPSFILE= 'infilename', which specifies the path and name of the MPS/QPS-format file. With this single parameter, the macro reads the file, converts the records, and saves the conversion to the default MPS-format SAS data set MPSDATA.

Running the following statements converts the fixed-format MPS file shown in Example 17.2 to the MPS-format SAS data set MPSDATA: 

%mps2sasd(mpsfile='example_fix.mps');
proc print data=mpsdata;
run;

Output 17.4.1 displays the MPS-format SAS data set MPSDATA.

Running the following statement converts the free-format MPS file shown in  Example 17.3 to the MPS-format SAS data set MPSDATA: 
            


%mps2sasd(mpsfile='example_free.mps');




The data set is identical to the one shown in Output 17.4.1. 
            

            
In the following statement, when the free-format MPS file is converted, the length of the variables field2, field3, and field5 in the SAS data set MPSDATA is explicitly set to 10 characters: 
            


%mps2sasd(mpsfile='example_free.mps', maxlen=10, format=free);




If you want to save the converted data to a SAS data set other than the default data set MPSDATA, you can use the parameter OUTDATA= mpsdata. The following statement reads data from the file example_fix.mps and writes
               the converted data to the data set PRODMIX: 
            


%mps2sasd(mpsfile='example_fix.mps', outdata=PRODMIX);
