Of constants and variables

Hi

A very simple question (couldn't find the answer in the Help of BlackBox).
I want to create a string as a lookup table, so I want to make it a
constant. e.g.

    CONST Encodings = "01230124022455012623017272";

But then, since I want to use it as a lookup table, I want to access it
with an index, e.g.

    ch := Encodings[i];

Unfortunately, the compiler tells me this is a no-no. What exactly is the
reasoning behind this rule?

Thanks.
