Declaring array size

Is it possible to re-size an array after the it has been declared as '0' size in Globals? E.g:

Sub Globals
Dim Type(x,y)reducedArr (0) As Int32
End Sub

Sub Calc
reducedArr () = Array (100?)
'can an array size of 100 be declared here without assigning any values to the array elements?
End

Yes. See here Variables and at the main help: Basic4ppc - Main Help

The actual code is:
Structures in Basic4ppc are actually arrays. The last dimension size should be equal to the number of parameters (2 here).

thanks, that would have taken me a while to figure out
