Thanks, I know what we're talking about.

Internally, QB does something much like VAL on the numeric constants in your program. Since this is done ONCE (per constant), before you run the program, there's no way to measure it directly with TIMER.

In other words, your program times two identical FOR loops. Mine times the actual conversion from decimal to binary, compared with hex to binary, which is what I wanted to show.

The difference per conversion is a few microseconds, anyway. It isn't worth worrying about. But it is there.
