SAS Temporary Variables

[SharonO]

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.
