From New CPS615 Foils-- 28 August 95 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Nancy McCracken and Geoffrey C. Fox
A Boolean array -- here called L -- can determine a "context" in which a data-parallel operation is evaluated
This example gives a final array with undefined elements and corresponds to
Fortran 90 selection statement
