Subject: Re: Multi-dimensional dynamic arrays

Data structures are, by definition, part of contiguous memory.
Therefore, it doesn't make sense to put the BASED keyword on a subfield
of a data structure. BASED controls the area of memory that something
is located in, and if it MUST be contiguous memory (as is the case of a
DS) then there'd be only one possible value for BASED.

Having said that, what you're trying to accomplish is certainly possible
-- just not the way you're approaching it.

You can put a POINTER in a data structure. Then have a separate array
that's based on that pointer -- this will result in what you're looking
for... a variable-length array that's particular to an element of a
parent array.

Ok, so I can't have a dynamic array with a subarray that is also
dynamic (more specifically, I can't have a subfield with the Based
keyword). I was curious if this would be something that may be
possible in the future - or if it's simply not possible. Just
throwing this out there to get thoughts.
