 /* Program environment:
 
-   Two environments are available. VEA (or virtual environment

+   OEA (perating).  The former two are environment that users would

+   base) while OEA is what an operating system expects to see.  By
    setting these to specific values, the build process is able to
    eliminate non relevent environment code
