Hello again everyone  
I still come back here for some more guidance. 
  
I have a big pile of variables/constants that I need to be selected depending of the previous variable/constant. 
  
Something like this: 
 Global $pos[1][4]
$pos[0][0] = 35, 30
$pos[0][1] = 110, 30
$pos[0][2] = 185, 30
$pos[0][3] = 260, 30
If $variableA = yes Then
  $pos[0][2] = $pos[0][2] - 0.1
EndIf
  
This clearly wont work, but is more of a suggestion to what I want to happen. 
The outcome should then be $pos[0][1] 
  
Is this possible? 
  
Kind Regards, 
Akarillon
