VARS

stack

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.

VARS is available since version 2.0.0.
