Hello David (and all others),

Now I read this thread I was wondering how I could solve my printf-
problem. I have a procedure that prints out data in a huge 2D array. I
cannot know beforehand how much data has to be put into the file (That
depends on how my research is going on and if I knew that beforehand,
it wouldn't be research). I used:

dataline = strjoin(string(data[*,0])) ; All rows should have equal
length
width = strlen(dataline) > max(strlen(headerlines))
openw,lun,'filename.dat',/Get_Lun,Width=width

And because my data consists of doubles and I use default format
everywhere, I see that my width is 16 times the number of data
columns. My width was 160. Now I wrote such a file and I see that all
my data rows are cut at 9 values. The line is 144 long and the next
line (containing the tenth column) is 16 long. This also happens for
other number of columns. I tried to add one to the width for safety,
but that does not work.

Why does this not work and can anyone help me?

Kind regards,
Joost Aan de Brugh
