TEMPORARY.
TEMPORARY is used to make the effects of transformations
following its execution temporary. These transformations
affect only the execution of the next procedure or procedure-like
command. Their effects are not be saved to the active dataset.
The only specification on TEMPORARY is the command name.
TEMPORARY may not appear within a DO IF or LOOP
construct. It may appear only once between procedures and
procedure-like commands.
Scratch variables cannot be used following TEMPORARY.
In Example 13.4 there are two COMPUTE transformation. One
of them immediatly follows a TEMPORARY command, and therefore has
effect only for the next procedure, which in this case is the first
DESCRIPTIVES command.

Example 13.4: Running a COMPUTE transformation after TEMPORARY
The data read by the first DESCRIPTIVES procedure are 4, 5, 8,
10.5, 13, 15. The data read by the second DESCRIPTIVES procedure are 1, 2,
5, 7.5, 10, 12. This is because the second COMPUTE transformation
has no effect on the second DESCRIPTIVES procedure. You can check these
figures in Result 13.2.
