[A83] Re: Changing number of free mem
Hmm, yes maybe, but the VAT start address is fixed (FE6Eh on 83-). So if you change the end pointers to FE6Eh, it should work. One side effect is that each variable type then seems to take up 0 bytes. In reality this isn't the case. This can be partially overcome by changing those pointers to some lower address, because the first entries are (probably) such permanent system vars. Permanent programs like prgm! and prgm# aren't detected then.
