whats going to happen if i use this code

I am still fairly new to programing and i have a few ir rangers that i want to use on my robot. I have hooked one of them up to the OOpic's
regulated supply voltage and i would like to know in advance if this program could tell the servo's to move in two directions at once and possibly screw them up
' This program reads the Sharp GP2D12 sensor ' It demonstrates the use of an oA2D object ' and an oDio1 object.
'this is an expiremental program that uses a singel ir ranger ' to make the 'robot turn left when it reaches something, i hope it works '------------------------------------ Dim irf1 as new oA2D
Dim S1 As New oServo Dim S2 As New oServo Dim CenterPos As New oByte Dim x as New oWord Dim y as New oWord
'----------------------------------------------------- Sub Main() OOPic.Node = 1 CenterPos = 31 Call Setup Do     S1 = CenterPos     S2 = CenterPos
Call GoRight y = 100 Call Delay
Call GoForward y = 100 Call Delay
Call GoLeft y = 100 Call Delay
Loop
do if irf1.value > 100 then Call GoReverse else
end if loop
End Sub
Sub Setup()
S1.Ioline = 3 S1.Operate = cvTrue S1.Center = CenterPos
S2.Ioline = 12 S2.Center = CenterPos S2.Operate = cvTrue S2.InvertOut = cvTrue
Oopic.ExtVRef=0 irf1.ioline=8 irf1.operate=cvtrue
End Sub '--------------------------------------- -----------
Sub Delay() For x = 1 To y:Next x End Sub
Sub GoForward() S1 = 0 S2 = 0 End Sub
Sub GoReverse() S1 = 53 S2 = 53 y = 100 Call Delay End Sub
Sub GoRight() S1 = 53 S2 = 0 End Sub
Sub GoLeft() S1 = 0 S2 = 53 End Sub

by the way the ir sensors are sharp gp2d12 and the servos are modified
