The problem you're seeing is that you have a variable (say, X) with 
lines like
2,5,e
and you try to split it ("split X by CR and comma").

you're hoping for
X[2,5] = e

But what you'd actually get is
X[2] = 5,e

because split takes the *first* instance of the split char (in this case 
comma)

The problem therefore is that you have the same char(",") for the split 
delimiter as for the array dimension delimiter.

It's not a bug, and it's not a general requirement - it's just a 
restriction for doing the split in the way you are trying to do it.
