Specifying an input file

[Bruce F.]

For some reason, the DSC approach didn't work for me, but
now I can see why there would be security concerns. The
use of a "/SubFileDecode filter" works like a charm and
solved my problem.

Sometimes I just need that bit of direction as to where to
look in the imposing manual.  Thanks for the help.
