Query activity log to get counts of tapes written to and read from

I am trying to write a script where I can get the numbers of tapes written to and read from during different TSM processing. I want to know not only the number of tapes checked in and checked out but how many tapes were written to for migration and written to and read from for reclamation. From what I can these are the messages I need to look for.

ANR0512I - input volume - tapes read from?
ANR0513I - output volume - tapes written to?
ANR6696I - number of tapes checked out?
ANR6682I - number of tapes checked in?
ANR1040I - number of tapes reclaimed?

Is this correct?

Is the 512 message the one for tapes begin read from. Is the 513 message the one for the tapes being written to? Am I correct about the other messages?
