If the current point of execution is in a user-defined function, or a Local or Parameter JSL function body, then the Local namespace is used for creation when Default Local is specified. However, the reference rule is unchanged.

If the Names Default To Here mode is on, JMP looks for the variable in these locations:
If the Names Default To Here mode is off, JMP looks for the variable in these locations:
