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.
