Octal, Hex, Binary

In QBASIC, we have

&O (ampersand, letter o) for octal (a plain ampersand also works)
&H (ampersand, letter h) for hexadecimal
The LEN function for unary [LEN("*****") = 5]

It would make sense to add &B for binary (as well as the function BIN$) to QB64.


Other random ideas for random base support:

Add an optional paramater to val and str:

VAL("11110", -2) = 10

And then we could add complex numbers, allowing base -2i:

STR$(CMPLX(7, 6)) = 7+6i
STR$(CMPLX(7, 6), CMPLX(0, -2)) = 10333
