ermm....

that may possibly be the most complicated way to do anything i have ever seen..

a button is nothing more than a if-then loop

example, using p1_sw_trig :
(the trigger swich on the joystick plugged into P1)
---------------------------------------------
panicbutton: 'lables the loop (neatness)
if p1_sw_trig = 1 then mysub: 'if button is pressed then goto sub
goto endsub: 'if it isnt.. then dont

mysub: 'put whatever you want the
out 8 = 1 'button to do here
out8 = 1 'this example Turns on some LED's
out9 = 1
out10 = 1

endsub: resumes the rest of the code


----------------------------------------------
as for infinite loops.. you really cant do that unless you use a do while loop, wich pretty much is the same structure. Rbayer posted a discription of the commands in the Pbasic programming section, you may want to check that out!

and you may want to avoid the Serin/out things.. you really dont need more than 2 at most
