You don't say what kind of array (byte? 32-bit int? 64-bit int? variant? structure?) and obviously that determines the size of each element and thus the biggest array that will fit.

This code runs for me without issuing an error:

Code:

      HIMEM = PAGE + 200000000
      DIM array%(40000000)

That's 40 million elements, which is 100 times the size of yours!
