I don't understand, how do you write them separately

Yeah, it seems dimensions are not written. You need to write them separately.

I guess Interger[] does not serialize its dimensions.

if I have a multi dimensional array and write it as an object, then read
it back it becomes a single dimensional array.

The number of entries remain the same, just the dimensions are lost.

I don't know if this a bug or a feature?

sample script

-----------------------------------------------------

#!/usr/bin/env gbs3

Dim a As New Integer[5, 5, 5]
Dim b As Integer[]

Dim x As Pointer = Alloc(5000)
Dim mfile As File

mfile = Memory x For Write
Write #mfile, a As Object
Close mfile

mfile = Memory x For Read
b = Read #mfile As Object

Print Subst("Before saving array  count=&1, Dim=&2", a.count, a.dim)
Print Subst("After reading array  count=&1, Dim=&2", b.count, b.dim)   '
they don't match

Quit 0
Catch
Error "Script Error >";; error.text & "\n" & error.where
