Extracts all variables used in a macro. The VARS function scans the macro for occurrences of LOAD, STORE or CSTORE functions and inspects the associated variable name. If such a name is not an explicit STRING, the call to VARS will fail with an error.

The list of symbols is sorted according to the number of occurrences encountered, decreasing.
