SAS: How to output only the part of PROC CONTENTS that displays the variables in the data set?

Question

I'm in a beginner SAS class and we are required to display only the section of the PROC CONTENTS output that shows the variables in the dataset. For example, when you do

proc contents data=whas.heart3;
run;

The output is 3 tables. The 3rd table is titled:

Alphabetic List of Variables and Attributes

I need to figure out how to modify the above code to display only that 3rd table.

Answer 1

Out put is delivered via the Output Delivery System (ODS). Use ods trace on; and the system will tell you what is being delivered. In this case, Variables is the table you are looking for.

Use ods select Variables; to tell ODS to ONLY deliver the variables table. Then reset to default (ods select default;) for other procedures.

ods select Variables;
proc contents data=mydata;
run;
ods select default;
