[REBOL] Suspected bug Re:
From: galtbarber:mailandnews at: 11-Aug-2000 18:30
when you do something like this:
foreach someword someseries [
print someword
]
then someword is set to the values
of someseries, but only within the code block
of the foreach loop.
I think there is a new context created for the
foreach invocation, and in that context
the value of someword is indeed repeatedly
set to each element of someseries.
Notice that you won't be able to see
someword outside the foreach loop before
or after it, although you may be able
to see something if someword has
a value in the enclosing, possibly global context.
This is actually a good feature of rebol, I like it.
In other languages like c, pascal, or basic,
you can see the looping variables value after
the function executes, and in large software
you have to worry about clobbering some other
variable. But here you know that whatever
word you choose to use with foreach will only
be redefined within the code block, and not
anywhere else.
Now, doindx1 is defined much earlier,
and it has a code block which when created
will have find initial to be a local variable
of the run function, so that is what is bound
there inside doindx1 when the function
creation is evaluated.
To do what you want, you would have to move
doindx1 down into the foreach loop,
or else pass it as a parameter, or else
don't use foreach, or else use some other
global variable.
