Subject: Null Range in Unconstrasined Array

Message-ID: <f237670b-ade0-461f-9d02-5eff803e91bc@p10g2000prm.googlegroups.com> (raw)
If I have an unconstrained array type 'My_Array_Type' and declare an
instance of it as:
My_Array : My_Array_Type (1 .. 0);
then the LRM tells me it is a null range:
3.5 (4): A range with lower bound L and upper bound R is described by
“L .. R”. If R is less than L, then the range is a null range, and
specifies an empty set of values.
What, exactly, is My_Array (forgive the language) pointing to?
Is any memory allocated to My_Array?
