Dear group, I am running Mathematica 6.0.3 on a Mac Pro with 4 Gig memory. I have fortran binary files that I can read in correctly (numbers of order 10^6) using Import[...,"Real32"]. But for larger problems, the size of the binary file is about 80 Mb, all memory is used (if i hit top, VSIZE is 17G) and only 2% of the CPU are used, so it basically can not handle the file. Is there a way to decrease the precision at which the file is read in, for my purpose the precision does not have to be very high? Thank you Jan
