Humm, I don't think so, since the problem is that the file
is filling up the character buffer.
I think the usual solution it to open this file in some
kind of word processor, turn on word wrapping, and save
the file with some reasonable length lines. But some word
processors won't allow you to load a line of that length
either.
In that case, I think you have to make a large byte
array and try to read the data that way, then process
the byte array to obtain the data. I guess I would
try something like this.
OpenR, lun, 'myfile.dat', /Get_Lun
info = FSTAT(lun)
data = BytArr(info.size)
ReadU, lun, data
Free_lun, lun
actualData = Float(StrSplit(String(data), /EXTRACT))
Cheers,
David
