TOT(0 seems broke

In this scenario, they are basically equivalent.

However, you can use TOT() in other ways, such as

    xx = tot(foo) * tot(bar)

which is definitely not the same as

    xx = xx + foo*bar

(It is the product of the sums, not the sum of the products.)

It is also part of a set of aggregate functions, like MIN(), MAX(),
and AVG(), and may make for "cleaner" code.

Also, here's something you can do with TOT() that will delight and
confuse everyone here.   :-)

      If:  foobar eq "Y"
    Then:  xx = tot(foo)
      If:  foobar ne "Y"
    Then:  xx = tot(bar)

What would you expect "xx" to hold?  I'll tell you right away that
it is _not_ the same as

      If:  foobar eq "Y"
    Then:  xx = xx + foo
      If:  foobar ne "Y"
    Then:  xx = xx + bar
