It looks like you have a subroutine called exec_select() that returns a reference to an array of hashes. Updated: underlined text added due to pedantry ;)

@{ exec_select( $sql ) } refers to the list returned, [0] accesses the 0'th element, ->{ home1} dereferences the hash (of the 0'th element of the list), and assigns that hash value to your %Aoh hash, specifically the testa key of that hash.

HTH
