Bob - you've lost me here? I suspect there something really basic that one
of us doesn't get - a lost in translation thing.
Environment varaibles are used to pass information between applications ie
the Shell and Revolution or Apache and Revolution - I am pretty sure you
wo"t need them for what you need?

Which languages do that? Most of the time you really don"t want a global
scope for variables. In fact I try to never use globals. One thing i really
wish for is to be able to make functios and commands private when used in
libraries - I"m a bit lost on what you want here?
This I can use to mimic a kind of "global" variable system without

You can put a global declaration outside of a handler - that is at the top
of any script. So it does not need to be in every handler:
put "hello" into test
return test && "world"
