[ic] Accessing scratch variables in perl code

[Tim Nelson]

Not sure of the difference here, but I had some code
that was working with $Vend::Scratch->{variable} on IC
4.6 and when I moved it up to IC 4.8 I have to use
$::Scratch->{variable}.

1. Can someone explain difference to an Interchange
newbie?

2. Is there a _standard_ way to refer to [scratch] (as
well as other data) items in Perl code?

Thanks. Tim
