VAS Log tape readout numbers

[Donet]

When I start FSX SE with the FSUIPC log tape running at the top of the screen I start of with a reading of around 1911800.  After flying for a while it drops down to 1500000 and in heavy scenery areas like Seatle in Orbx Pacific NW it drops to 600000.
My question is what do these numbers represent.. Is it VAS memory and are they bytes or megabytes or what?  As you can see I'm not a computer guru but I'd like to know so that I can see how they might relate to numbers I see in Task manager

Sorry, what is this?

Like John, I've no idea what you mean by "log tape".

Perhaps the "log tape" means logging to title bar or to a "green line" display.
In any case the VAS number is in kilobytes -  024C Available FS memory in kilobytes (updated every 10 seconds)
That is.. If 024C is used.
Other memory outputs ( from FSUIPC# Offsets Status.pdf )
0258 Memory currently assigned to FSUIPC4 (including WideServer) This is in Bytes.
0290 Maximum available FS contiguous memory block in kilobytes (updated every 10 seconds).
