The problem is that you have to specify your variable as
a double before reading. Someone already pointed
this out so . . .

Just thought I would defend DC_READ_FREE. It is one
of the most useful routines in all of PV-Wave. It does
have several quirks but I can't even imagine reading
column data the old OPENR way.

I have never messed with READ_IMAGE (nor do I care to)
so I really shouldn't attempt to comment on it.
