How can I display/output/view the temporary variables SAS creates?
Examples:
by city state zip
ouput
city state zip first.city last.city first.state last.state first.zip last.zip
There are a couple of possibilities, both subject to this "feature": once the DATA step ends, those variables no longer exist.
One possibility: add PUT statements in the DATA step that write the variables to the log. Example:
if _n_ < 20 then put city state zip first.city last.city first.state last.state first.zip last.zip;
Another possibility: copy the variables, and store the copies in the data set. Example:
first_state = first.state;
last_state = last.state;
You can examine them after the DATA step is complete.

As a learning exercise you can put the entire PDF and observations into an associative array.
