Flowchart meaning

Does someone know what ‘tempvar’ means? And what can I do with this?

It just seems short for “temporary variable”, it is not a special word or anything, just the chosen name for that variable. Which usually means that it is just a variable used to temporarily hold a value.

Considering that the language used is incomprehensible for me, I may be wrong, but there is still no special word like that, also because the special words are english based.
