After having assigned a target to a reference Glossary: Variable, var_refvariable, all references to List functions: thisthis Glossary: Variable, var_refvariable actually refer to Flow control: if … then
Flow control: try … thenthe assigned destination. Even "Instructions: deldel <ref_var>" refers to List functions: thisthis destination.

Setting a reference to a reference Glossary: Variable, var_refvariable makes it point directly to Flow control: if … then
Flow control: try … thenthe target's target.
