2 getch lines at once

[MeTaLPyTHoN]

Hey... Im a pretty novice programmer but rather intrested in it and advancing my skills, but for the moment i dont know if what im asking about is possible in turing, or how to do it, so i figured this would be the place to come... im trying to make a pong game for computer science, and cant figure out how to get the computer to accept 2 key press values at once, right now im using a process for each paddle, and they work, but only one at a time, like only one paddle will move at one time bcuz it wont read 2 getch statements at one time... is there an easier statement for this or are processes the wrong way to go (forking was my only guess at getting 2 things to ahppen at once).. anyway, heres the code, if anyone has suggestions, they would be much appreciated:)
setscreen ("graphics:700;500")
var screen, paddle1y, paddle2y, paddlepic : int
drawfillbox (0, 0, 10, 50, 10)
paddlepic := Pic.New (0, 0, 10, 50)
cls
screen := Pic.New (0, 0, 10, 10)
paddle1y := 0
paddle2y := 0

proc drawBackGround ()
Draw.FillBox (0, 0, maxx, maxy, 7)
Draw.Line (70, 0, 70, maxy, 10)
Draw.Line (maxx - 70, 0, maxx - 70, maxy, 10)
Draw.Oval (round (maxx / 2), round (maxy / 2), 75, 75, 10)
Draw.Line (round (maxx / 2), maxy, round (maxx / 2), maxy - 100, 10)
Draw.Line (round (maxx / 2), maxy - 200, round (maxx / 2), maxy - 300, 10)
Draw.Line (round (maxx / 2), maxy - 400, round (maxx / 2), 0, 10)
end drawBackGround
proc saveScreen (var screen : int)
screen := Pic.New (0, 0, maxx, maxy)
end saveScreen
proc drawSaved (screen : int)
Pic.Draw (screen, 0, 0, picCopy)
end drawSaved
proc drawpaddle (x, y : int)
Pic.Draw (paddlepic, x, y, picCopy)
end drawpaddle

process movepaddle1 ()
var select : string (1)
setscreen ("offscreenonly")
loop
loop
getch (select)
if select = "a" then
paddle1y += 5

if paddle1y >= maxy - 50 then
paddle1y := maxy - 50
end if
exit
elsif select = "z" then
paddle1y -= 5
if paddle1y <= 0 then
paddle1y := 0
end if
exit
end if

end loop
drawBackGround
drawpaddle (60, paddle1y)
drawpaddle (maxx - 70, paddle2y)
View.Update
end loop
end movepaddle1
process movepaddle2 ()
setscreen ("offscreenonly")
var select : string (1)

getch (select)
if select = "k" then
paddle2y += 5
if paddle2y >= maxy - 50 then
paddle2y := maxy - 50
end if
exit
elsif select = "m" then
paddle2y -= 5
if paddle2y <= 0 then
paddle2y := 0
end if
exit
end if
end loop

you can't. not like that, anyway, not with getch. you'll need to use Input.KeyDown... i think there's a tutorial on it in teh tutorials section so you should check there. if ther isn't, try the turing reference (F10) and look up Input.KeyDown, it does a pretty good job of explaining it.

thanks a bunch!

here is what i ended up with, works like a charm:> i kept the processes and used the input.keydown

setscreen ("graphics:700;500")
var screen, paddle1y, paddle2y, paddlepic : int
drawfillbox (0, 0, 10, 50, 10)
paddlepic := Pic.New (0, 0, 10, 50)
cls
screen := Pic.New (0, 0, 10, 10)
paddle1y := 0
paddle2y := 0

proc drawBackGround ()
Draw.FillBox (0, 0, maxx, maxy, 7)
Draw.Line (70, 0, 70, maxy, 10)
Draw.Line (maxx - 70, 0, maxx - 70, maxy, 10)
Draw.Oval (round (maxx / 2), round (maxy / 2), 75, 75, 10)
Draw.Line (round (maxx / 2), maxy, round (maxx / 2), maxy - 100, 10)
Draw.Line (round (maxx / 2), maxy - 200, round (maxx / 2), maxy - 300, 10)
Draw.Line (round (maxx / 2), maxy - 400, round (maxx / 2), 0, 10)
end drawBackGround
proc saveScreen (var screen : int)
screen := Pic.New (0, 0, maxx, maxy)
end saveScreen
proc drawSaved (screen : int)
Pic.Draw (screen, 0, 0, picCopy)
end drawSaved
proc drawpaddle (x, y : int)
Pic.Draw (paddlepic, x, y, picCopy)
end drawpaddle

process movepaddle1 ()
var select : array char of boolean
setscreen ("offscreenonly")
loop
loop
Input.KeyDown(select)
if select ( 'a') then
paddle1y += 5

if paddle1y >= maxy - 50 then
paddle1y := maxy - 50
end if
exit
elsif select ('z') then
paddle1y -= 5
if paddle1y <= 0 then
paddle1y := 0
end if
exit
end if

end loop
drawBackGround
drawpaddle (60, paddle1y)
drawpaddle (maxx - 70, paddle2y)
View.Update
Time.Delay(10)
end loop
end movepaddle1
process movepaddle2 ()
var select : array char of boolean
setscreen ("offscreenonly")
loop
loop
Input.KeyDown(select)
if select ( 'k') then
paddle2y += 5

if paddle2y >= maxy - 50 then
paddle2y := maxy - 50
end if
exit
elsif select ('m') then
paddle2y -= 5
if paddle2y <= 0 then
paddle2y := 0
end if
exit
end if

end loop
drawBackGround
drawpaddle (60, paddle1y)
drawpaddle (maxx - 70, paddle2y)
View.Update
Time.Delay(10)
end loop
end movepaddle2

drawBackGround
fork movepaddle2

For a new programmer , looks like you pic e dup the language pretty well , keep up this good code , all these mew people ar ejsut amazing me with what they can do ,
