Ver. 6940 CAS constructs

[Tim Wessman]

Unfortunately not due to the limited scope of the documentation work that could be done for this release. (basically, the whole time was used to rework the manual from one format to another enabling quicker updates/translations moving forward)

It is pretty simple though. Anything inside that block is executed by the CAS just as if you typed it in on the CAS screen any time you compile the program source file.
