Finally got round to testing my thoughts.

On my FreeAXP (no JIT) setup I get the following with your code:

Basic:
   12.3182 million integer operations per second
   14.1572 million floating point operations per second
    0.0080 million string operations per second


I then changed the integer bits to append the % to all integer 
constants, and now get:

Basic:
   31.6586 million integer operations per second

It shows how BASIC can be slowed down not doing that!
