Source file in compressed tar file. To install all files under Unix, type: tar xzvf progsf90.tar.gz and if this does not work: gunzip progsf90.tar.gz tar xvf progsf90.tar To retrieve files under Windows, use gunzip and tar included in the winbin directory: gunzip -d progsf90.tar.gz tar xvf progsf90.tar Note: Program and data files are prepared in Unix text form (LF but not CR). A conversion to LF-CR format may be needed for some Windows f90/f95 compilers to work correctly.
