Details

Some of the information, such as the filenames and access permissions, that is generated by the DATASETS procedure depends on your operating environment. The information generated by the CONTENTS statement also varies according to the device type or access method associated with the data set. If you specify the DIRECTORY option in the CONTENTS statement, the directory information is displayed in both the log and output windows.

Example

The following SAS code creates two data sets, grades.sas7bdat and majors.sas7bdat, and runs PROC DATASETS on majors.sas7bdat.

options nodate pageno=1;
libname classes '.';

data classes.grades (label='First Data Set');
   input student year state $ grade1 grade2;
   label year='Year of Birth';
   format grade1 4.1;
   datalines;
1000 1980 NC 85 87
1042 1981 MD 92 92
1095 1979 PA 78 72
1187 1980 MA 87 94
;
run;

data classes.majors(label='Second Data Set');
   input student $ year state $ grade1 grade2 major $;
   label state='Home State';
   format grade1 5.2;
   datalines;

proc datasets library=classes;
   contents data=majors directory;
run;

The output of this example is shown in PROC DATASETS Example. The first page of output from this example SAS code is produced by the DIRECTORY option in the CONTENTS statement. This information also appears on the SAS log. Pages 2 and 3 in this output describe the data set classes.majors.sas7bdat and appear only on the SAS output.
