Bug in online version

In online version of RunBASIC there is a bug with executing "step" expression. For instance copy the code

for x = 1 to 20
y=x*3
if y>40 then EXIT FOR
next x
print "Final x value ";x
print "Final y value ";y

from page www.runbasic.com/docs/for_statement.html , section of "EXIT FOR". Then add "step 1" expression to the first line of code to obtain "for x = 1 to 20 step 1". Run that modified code in online version of RunBASIC - it will crush with "Runtime Error: EXIT FOR No loop to EXIT" error. But when You will run it using downloaded free version of RB, everything will be fine. The code will work correctly.
