What is a temporary array and how does it differ from permanent arrays?
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 |
