Daniel,
You might want to try using Visual Basic (or C, or C++) using the
supplied examples on the QP2 CDROM to write more sophisticated
scans. The QP2 scan language I do not believe is intended to
be a "real" programming language. Many TA functions are available
in the .dll supplied on the CDROM. And of course using a "real"
programming language, you have access to all the things you mentioned
above... arrays, strings, global variables (and some things you
didn't mention: mathematical functions lacking in the scan
language such as log, exp, sqrt).
I do think QP2 is the best EOD product out there [though I
have gone on tirades against them once-in-a-while myself :)]
