Most of the VP functions write 'baseline' and 'most recent capture' data
to files. I don't recall how it compares the data, but do not think you
can point them to your own array.

It would probably be easier/better to write your own test function that
captures the data and compares it to baseline data (which can be captured
using the same function). See the "SQAGet*" functions in Robot's SQABasic
online reference.
