proc in array, ...but is it the solution?

[PMunch]

You can definitely put procedures into an array:
    
    
    var arr: array[1, proc(x: float): float]
    arr[0] = proc(x: float): float = (x*2.0)
    
    echo arr[0](100)
    
    
    Run

Whether or not it'll help you I'm not sure.. I think there is a better way to 
do what you're trying to do, but I haven't given it much thought.
