Thanks for the answers everybody. Yes I do need to use an ASCII format,
HDF is not an option for me. I also need to parse the file manually -at
least partially-, that is the other reason.

printf, 2, '$(2000F)'
command is actually all i need. But I have one other silly question,
what if the size of the array is parametric? I tried to put the variable
name but that didnt work. Just for the record, I come from neither C nor
fortran school. No programming skills, unfortunately. I measure bones
:-)
Best,
Murat
