Hello Vince,
I don't have Adobe Acrobat Pro, and I don't know how it is
scriptable. Even if it is not very scriptable, it should be able to
open files with a script, and it should be possible to send the
"sendkeys" commands that you describe with the user interface
scripting. But then, it would be simpler to use AppleScript than
Perl. I think the best place to ask such questions is the
MacScripting mailing list <http://listserv.dartmouth.edu/scripts/
wa.exe?SUBED1=macscrpt&A=1>. But to develop AppleScript scripts, you
should use a Mac...
Good luck, and
Best regards,
