A scan through jss files shows examples in several. I'd say the
directive would be useful if you're calling a function you know exists
among the jsb files you're loading but the compiler doesn't get it. An
example would be if a.jss Uses b.jss which calls a function from
a.jss. This directivve seems to be new in JAWS 13.
Cool idea anyway.

Hi folks,
I stumbled across the following line of code in QuickSet.jsd recently,
and a rather terse explanation buried in FileIO.jss. However, it seems
to be undocumented in the FSDN. Grepping the all users settings\enu
directory, There are a pile of scripts that use the Import directive.
I can't say I truely grok it, but it appears that the Import command is
used for getting the Script Manager to load up function declarations
(from jsd files) that are deeply nested in the script binary load scope.
I always thought that the Script Manager automatically loaded the jsd
files associated with binaries referenced using the Use directive. I am
assuming that Import is needed because the compiler isn't actually
clever enough to recursively scan through "Used" jsb files to find all
the associated jsd files necessary to provide all the required function
declarations, in case the top level script file calls a function buried
2 or more levels down in the scope (excluding functions in default.jss
whose documentation one would expect the Script Manager to always have
on hand).
Is anyone else aware of this or have I just been living on another
planet for the last few years?
Cheers,
Andrew.
