Reeza, you're supposed to use this "preview" period to answer questions, not ask them!

Are you asking about these within the scope of DS2? Here's a simple comparison.

Temporary Array	Variable Array
set of temporary data elements	set of references to variables in the PDV
created with a DECLARE statement	created with a VARARRAY statement
may be declared in local or global scope	must be declared in global scope
similar to arrays seen in other languages	similar to arrays of pointers/references seen in other languages
in DATA step, created with ARRAY statement with _TEMPORARY_ argument	in DATA step, created with ARRAY statement

I was testing the ask a question interface. I ran into problems when posting but I don't recall what it was anymore
