yep,

If IsActive(INPUT1) And a=0 Then
SetOEMDRO(3,100)
SetUserDRO(2000,1)
Message("Slow Jog Rate set to 3")
Else
SetUserDRO(2000,0)
End If

Is this logic correct?
I don't think this only sets the OEMDRO once per button press, but every other running of the Macropump, which could be 200 times a second. It is not crictical in this case and would not even be noticable, but if the latch is put in......
