Thanks to the people who helped but this is not working, quite
possibly to my lack of knowledge.

This global variable should gte be available (i.e., I don't have to
explicitly use the system unit), right?  I tried adding both
spellings suggested and also upgrading my FPC but this won't compile
(see below).  Are these globals documented somewhere (I've printed
all four PDF manuals and I don't recall seeing these) or do I need to
unpack the system unit source to browse them?

=====
A Congressman was once asked about his attitude toward whiskey.  "If you mean the demon drink that poisons the mind, pollutes the body, desecrates family life, and inflames sinners, then I'm against it. "

"But if you mean the elixir of Christmas cheer, the shield against winter chill, the taxable potion that puts needed funds into public coffers to comfort little crippled children, then I'm for it."
 
"This is my position, and I will not compromise."
