I've run into situations like this when I have a data description in a
separate
place from a data stream. For example, if I have a socket client that must
read
a data type before allocating the appropriate amount of space to read the
subsequent data.
The FIX function has a TYPE keyword to allow the creation of a scalar of a
particular IDL numeric data type.

I resemble the mark about missing obvious things :-) so I'll reply
that it seems to me all scalar variables in IDL match your
description. That is, any scalar variable can be of any type and
dynamic assignment is the norm, therefore the equivalent of make_array
for scalars would be completely redundant.
So, what obvious thing am I missing in your question?
