/---------------------/ / CDF V2.7 Features / /---------------------/ * Backward compatible with CDF V2.6: CDF V2.7 files have the same data structure as those of CDF V2.6. * Addition of user-friendly GUI CDF tools (except for CDFedit and CDFexport). The current command-line-based CDF tools are still available. * Addition of CDF Java APIs to allow users to develop platform-independent CDF applications in Java * Differences between CDF 2.6.7 (the last V2.6 release) and CDF 2.7 - Improved and more robust CDF library - CDF Java APIs can do everything the C and Fortran APIs can do plus the following: o Copy a variable with or without data o Newly copied variable can be stored in the current CDF or in a different CDF file o Copy data from one variable to another Documentation for the CDF Java APIs is available at http://nssdc.gsfc.nasa.gov/cdf/cdfjava_doc/index.html. The CDF V2.7 software distribution is available via anonymous FTP and DECnet for VMS systems, via anonymous FTP only for UNIX/POSIXshell systems, and via anonymous FTP and floppy disks for MS-DOS and Macintosh systems. For OpenVMS systems: 1) via anonymous FTP: "anonymous" account on nssdcftp.gsfc.nasa.gov (128.183.241.13) in `standards/cdf/dist/cdf27/vms'. 2) via HTTP Go to http://nssdcftp.gsfc.nasa.gov/standards/cdf/dist/cdf27/vms Download the files: cdf27-dist.bck cdf27-dist.fdl For UNIX/LINUX/POSIXshell (including Windows running Cygwin and Macintosh running Mac OS X) systems via anonymous FTP: "anonymous" account on nssdcftp.gsfc.nasa.gov (128.183.241.13) in `standards/cdf/dist/cdf27/unix-linux'. The files you need vary depending on what your needs are. Download the README file first and determine which tar file and installation instructions are needed. There are 3 tar files (i.e. cdf27-dist-all.tar, cdf27-dist-cdf.tar, cdf27-dist-java.tar), and each of these tar files comes in two different compressed formats. The file that has an extension of '.Z' is compressed with the Unix 'compress' command. The file that has an extension of '.gz' is compressed with the Gnu 'gzip' utility. The uncompressed `tar' file is for those systems running the POSIX Shell (on a VAX or Alpha) which typically does not have the `uncompress' utility. Use binary mode to transfer a compressed or an uncompressed tar file. For 16-bit MS-DOS systems via anonymous FTP: "anonymous" account on nssdcftp.gsfc.nasa.gov (128.183.241.13) in standards/cdf/dist/cdf27/dos. The files you need are README.DOS and `*.EXE' (self-extracting LHA files). Use binary mode to transfer the `.EXE' files. NOTE: The CDF Java APIs and tools are not available for the MS-DOS (not Windows 95/98/NT/2000) operating system. For 16-bit MS-DOS systems via floppy disk: Send a request to CDFSUPPORT with your mailing address and the type of floppy disk you are able to read. For 32-bit Windows NT/95/98 via anonymous FTP: "anonymous" account on nssdcftp.gsfc.nasa.gov (128.183.241.13) in standards/cdf/dist/cdf27/w32. The file you need is `CDF27.EXE' (a self-extracting WinZip file). Use binary mode to transfer the file. Once file is extracted, read the README.1st file to see the contents of the distribution. A new one, CDFTOOLS32.EXE is also an self-extracting program which contains each individual CDF tool program. It can be used to replace the MS VC++-based CDFso.EXE and CDFFsi.EXE programs distributed in CDF27.EXE. Cygwin is needed to run Curses-based tool programs, ie., cdfedit and cdfexport. For Macintosh systems via anonymous FTP: "anonymous" account on nssdcftp.gsfc.nasa.gov (128.183.241.13) in standards/cdf/dist/cdf27/mac. The file you need is `cdf27.sit.hqx' (a BinHex'ed self-extracting archive file). Use text mode when transferring the `cdf27.sit.hqx' file. Once files are extracted, read the README.1st file to see the contents of the distribution. For Macintosh systems via floppy disk: Send a request to CDFSUPPORT with your mailing address and the type of floppy disk you are able to read. The CDF documents are available via Web (html version) or anonymous FTP on nssdcftp.gsfc.nasa.gov under the standards/cdf/doc directory as compressed and uncompressed Adobe Portable Document Format (PDF) files. The documentation set consists of the CDF User's Guide (UG), the CDF C Reference Manual (CRM), the CDF Fortran Reference Manual (FRM), and the CDF Internal Format Description (IFD). The documents, except the IFD, are each approximately 200 pages. The IFD is about 50 pages. Availability of the CDF 2.7 documentation via anonymous FTP: The uncompressed PDF files are: cdf27ug.pdf (CDF User's Guide) cdf27crm.pdf (CDF C Reference Manual) cdf27frm.pdf (CDF Fortran Reference Manual) cdf27ifd.pdf (CDF Internal Format Description) These files should be transferred using binary mode. PDF files compressed using the `compress' utility are: cdf27ug.pdf.Z cdf27crm.pdf.Z cdf27frm.pdf.Z cdf27ifd.pdf.Z These files should be transferred using binary mode and are uncompressed by using the `uncompress' utility. Note that these files may not be usable on VMS systems. PDF files compressed using the Gnu `gzip' utility are: cdf27ug.pdf.gz cdf27crm.pdf.gz cdf27frm.pdf.gz cdf27ifd.pdf.gz These files should be transferred using binary mode and are uncompressed by using the Gnu `gzip' utility with the `-d' option. Note that these files may not be usable on VMS systems. Via hard copy: Send a request to CDFSUPPORT indicating which documents you need. We have a user support office for CDF that you should contact when you need assistance. For Email requests send to: Internet -- CDFSUPPORT@NSSDCA.GSFC.NASA.GOV (128.183.241.14) DECnet -- NCF::CDFSUPPORT (15578::CDFSUPPORT) Please let us know (via Email to CDFSUPPORT) if you get the distribution. We would like to know who has the distribution so we know who to contact when updates are available. CDFsupport
