[REBOL] Re: Variable not avilable out of a foreach
From: edoconnor:gm:ail at: 11-Dec-2007 13:20
With rebol, one often hears the (adapted) Einstein quote, "Make things
as simple as possible, but no simpler." The act of explaining
something can make it seem more complicated than it is. I think this
is the case with foreach and contexts.
foreach LINE database [get_data]
I think of LINE as a local function variable, owned by foreach. You
can use the variable only within the foreach expression. To use it
outside the scope of foreach, you need to assign the value of LINE to
a global variable. Anton's comments for techniques #1 and #2 provide
the common ways of doing this.
