I don't want to use memory for some of my arrays until their function is called for the first time. I tried doing it like this and it gave me an error:

+ Code Snippet

function FunctionName()
if array index valid(Array(0))=0 then dim Array(200) as boolean
else
 ..

If you're checking if an array index is valid, the array has to exist before you do so. Try using a global variable to check if the function has been called before, and if it hasn't, dim the array.

[edit]

Like this

+ Code Snippet

myfunction()
end

global arrayexist as boolean
function myfunction()
   if arrayexist = 0 then dim array(10)
   array(0) = n ^ 2
endfunction

Or an array to store if the array has been dimensionalized already.

+ Code Snippet

dim Array(1)

if Array(0)=0
 dim Temp1(50)
 Array(0)=1
endif

if Array(1)=0
 dim Temp2(50)
 Array(1)=1
endif
