Ah, yes, you have done your homework! That was my first
project in this vein! But I believed it had fallen into
obscurity after having not told anyone about it. How did
you come across my earlier work [Ian_Tindale]?

It's not so much a language as an alternate character encoding. You ought to be able to write a parser relatively easily. Is a prerequisite that each character is described using a two character code drawn from the set {0123456} if so, then you've got k^n possible code values or 7^2 = 49. You've used 36 of these on characters and numerics, and it looks as though you're reserving the 0x code-page for data-type mode-setting. 00 = String, 03 = Interpret Math, that leaves {01,02,04,05,06} for other functional purposes (presumably) and 6 values across x0 {10,20,30,40,50,60} So, how are you going to assign these remaining 11 operational codes in order to, for example perform execution management tasks like looping, branching, and the like?

Also, it looks as though you've got a language in a language here - (ADD 1 2) can be parsed and turned into a value, but that's using an encoding outside of your language. It's a bit of a cheat to say your language can do anything if all it's doing is (mostly) acting as a representational scheme.

If you're looking to do that, then binary is way ahead of you, having condensed everything into a bunch of ones and zeros.

Using 2 (hex-sided) dice, a 12 character alphabet can be built along frequency-of-occurrence, ie: the equivalent of an 'e' could be 6 (3+3, 1+5, 5+1, ...)

[zen_tom], I clearly state that the only values used are
"123456". This is because six-sided dice have six sides. I will
add a factorial function at some point in order to show how
it is done but this may be beside the point. In 2050, if your
AI does not know how to add two numbers then we are all
in real trouble.

It seems [zelah] has a fascination with using 6 characters.
We've already shredded your "Five" maths system. Your "6" programming system is no better. It's just a poorly thought-out relabelling of things that already work.
