I've taken Gene Wrights original work, put it in an XL sheet and added a few items:

There's a link to the file at the bottom of the page here:

I'll try to maintain it and add some more benchmark columns to it.

LOOP1()
BEGIN
 A:=0;
 REPEAT
 A:=A+1;
 UNTIL 0;
END;

Run for 1 minute, stop, recall A. Averaged 5 runs.

~582,000

LOOP2()
BEGIN
 FOR A FROM 0 TO 1E9 DO
 END;
END;

Run for 1 minute, stop, recall A. Averaged 5 runs.

~1,640,000

For an exact comparison with same program as 39gs.

LOOP3()
BEGIN
 1 STO A
 REPEAT
 A+1 STO A;
 UNTIL A <=0;
END;

Run for 1 minute, stop, recall A. Averaged 5 runs.

~440,000
