When the CONTROL_FUNC function is called for the first time, the default setting of
CONTROL NOSHRVARS prevents variables being shared to CONTROL_FUNC.
Accordingly, the value of &VAR_1 does not change. When the CONTROL_FUNC
function is called for the second time, the CALL statement enables variable sharing,
and so the value of &VAR_1 is changed.
