Embedded arrays are declared like this: Public ArrayOfStrings[5] As String
While normal arrays are declared like Dim ArrayOfStrings As New String[5] or Public ArrayOfStrings As New String[5] I can agree the documentation is maybe a bit strange... Embedded arrays take upp less space since the data they contain are directly allocated as a datafield in a class, but slower to use because a wrapper object holding a reference is created every time you use it. Embedded arrays can not be declarated as a local variable, because each value on the stack always take up a constant memory usage in gambas (32 bytes for 64-bit platform), and arrays can be larger than that. I suggest you should avoid embedded arrays. They are useful when you need to create a struct containing an array that should be passed to an external C function that expects such a struct, but not otherwise. /Emil 2012/5/6 RICHARD WALKER <richard.j.wal...@ntlworld.com> > Greetings to the list on a fine Sunday afternoon (should be outside > enjoying it instead of hacking on a new project!). > > I am having difficulty understanding the correct way to program with > arrays in Gambas 3.
