why not make the %len(myVaryFld:*MAX)

%len(myVaryFld:*DATA)

Because when I see %Len(xx:*DATA) it says to me "I want the length of the data", which we can already get with the ordinary %len() BIF. What I really want isn't the length of the data, it's the maximum length that will fit in the variable. Thus, %len(xx:*MAX).

This is different from %addr(). When I do %addr(xx)+2 today, it's my way of getting the address of the data portion of the VARYING variable. So %addr(xx:*DATA) makes sense to me in that case.
