As far as I know it simply replaces the constant variable with the value held by it. ie:

Open in online IDE

Const a = 32
Const b = 15
Print a

Becomes:

Open in online IDE

Print 32

So I think only the ones that are actually used have any impact on the program.

Interesting fact: A constant can actually be overwritten locally by functions:

Open in online IDE

Const a = 32
Print a
Print NotSoConst(16)
Function NotSoConst(a)
  Return a
End Function

And the same goes for global variables.
