Implied do loops in IDL [message #2267]

I have a need for implied do loops in IDL but they appear to be unsupported.
My need occurs when reading data from a file.

Here is an example:

In FORTRAN, the file was written as:

write(unit) n, (data(i), i = 1, n)

and read as:

read(unit) n, (data(i), i=1, n)

In this example, n is not generally fixed for every file record.
It seems that the only way to read such files is with implied do's.

Note that I am trying to avoid calling a FORTRAN routine at this
point. Does anyone know if "native" IDL can handle such reads
and writes?
