There may be a little confusion here too because unidata and some flavors in 
universe have vector math on by default, so for example:

001 A=1:@AM:3
002 B=2:@VM:9
003 CRT A+B

on unidata and universe in information flavor this will print  3]9^3, while 
universe in ideal or pick flavor will print 0. So I can see where someone might 
have an expectation that the = operator will also see vectors, but it doesn't. 
you need to use eqs.
