rednet.open("top")
while true do
term.clear()
term.setCursorPos(1,1)
print("REMOTE CONTROL CLIENT")
print("")
print("")
print("-MAIN CENTRALE")
print(" MAIN STORAGE")
print(" PORTA REATTORE")
print(" LUCI")
term.setCursorPos(1,4)
local event,param1 = os.pullEvent()
if event=="char" then
   print(")")
   if param1=="w" then
	l,r=term.getCursorPos()
	if l>4 then
	 write(" ")
	 term.setCursorPos(1,l-1)
	 write("-")
	end
   elseif param1=="s" then
	l,r=term.getCursorPos()
	if l<7 then
	 write(" ")
	 term.setCursorPos(1,l+1)
	 write("-")
	end
   elseif param1=="e" then
	l,r=term.getCursorPos()
	if l==4 then printMen(colors.white)
	elseif l==5 then printMen(colors.orange)
	elseif l==6 then printMen(colors.lightBlue)
	elseif l==7 then printMen(color.lime)
   end
end
end
end

the program freeze on the os.pullEvent and even if I press a key it won't continue can anyone help?

thanks

it don't freezes, you wrote an error! if the whole program is in a while loop, and it changes the selection, the program prints not changed values, but the start state is printed! so it selected an other option, then the while loop starts again, and it selected again the first option…
