reading data from file [message #49221]

Hi all
I'm facing this problem (probably for most of you this is not a
problem). I've a file of ascii data of the following form:
Some header of text, and then a unique column of data written down as
follow (for simplicity I put them all equal to 0)

0
0
0
0

0
0
0
0

0
0
0
0

ect...
I mean a series of column of the same lenght N repeated M times. They
represents a Matrix or a double-array of the form fltarr(N,M). If one
is used to gnuplot you can plot it with

splot 'file.txt' u 1

I would like to read it in IDL in order to plot the data but I do not
have idea how to implement it, taking into account the data file could
be of the order of 50 MB.
Sorry if this represents a question for dummies but any suggestion will
be appreciated
Regards
Nicola
