topas -P save output

hi

i have server monitor script which totally depends upon the output of TOP which works fine on HP.
now i am told to put same script on aix i found that topas -P produces same output but it doesnt redirect output to file i have to kill/terminate it. is there any other way to this.
as the script runs from cron every 10 mins i dont think killing topas command by kill command would be a great idea.
