Macro Scope Test with mp_assertscope

This script initializes a witness variable, captures the state of macro variables (snapshot) via %mp_assertscope, executes the %example macro, then compares the final state with the initial state to ensure that no macro variables have been unexpectedly created or modified (scope leak).

Data Analysis

Type : CREATION_INTERNE

No external data source used. The test relies solely on the management of macro symbol tables.
