5.2) More Than One Test (cont'd)

On the other hand, if you only require one of the two tests to be satisfied then use .or.. For example:

       if ( a > b .or. c < d ) then
          print *, ‘a is greater than b or c is less than d’
       endif

The first test that is true will enable the code to progress to line 2 (if the first test a > b is true then c < d is not even tested).
