OK, so you're using AIX, not everyone is familiar with it, so consider providing sample input to the Perl script
svmon
   -P, mem usage for the following PIDs
   -t$n, Displays memory usage statistics for the top $n processes

[download]
So that's our input. We skip the first line by insisting that $. (input line number) is 2
Then allow following lines with the OR $& (last pattern match, from line 2 on exists)
There is also a redundant check on !$s++ which only can return true when $s=0
however if the line consists of dashes "-" reset the counter to zero.

For more precise answers try adding the input, the result of svmon -Pt15 to the enquiry.
Hope this helps.
UPDATEBy the way this code is horribly inefficient and seems to be written for obscurity more than for effectiveness

print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."
