Yes, I read over the code... looks like a good step forward.
The grammar got not much more complicated (just a handful of error  
cases added).

But the image successfully recompiles (of course), we now need to  
test it in real life
to see if it it complete and does not break anything.

Yes, it's definitely moving in the right direction. But we need to  
tweak the
error messages a little more.

Examples:

1 + Negative number, string, variable or character expected ->
(why negative number?)

(1 + 2 Right parentheses expected ->

Good.

1+ 2 Period, right box bracket or right curly brackets expected ->)

Hmm... period is ok. but } is not right... the old compiler just says:
1+ 2 Nothing more expected ->)

if we add a }

1+ 2 Right box bracket expected ->}

and this then:

1+ 2]

does not produce any error...
