1.7 CDF Toolkit

A set of utility programs are provided with the CDF distribution which allow a user to perform a variety of operations on CDFs without having to write an application program. Each toolkit program is described in detail in Chapter 3.

The available toolkit programs are as follows:

CDFedit

[]CDFedit has replaced CDFbrowse. The alias/symbol CDFbrowse still exists in the ``definitions'' file on UNIX/VMS systems but now executes CDFedit in a browse-only mode. Allows the display, creation, and modification of attribute and variable data in a CDF.

CDFlist
Allows a sequential ``flat'' view of filtered variable data. CDFlist also allows the subsetting of a CDF (creating a new, smaller CDF).
CDFwalk
Allows direct and sequential access to related variable values.
CDFconvert
Allows the format, encoding, and majority of a CDF to be changed. In all cases a new CDF is created. The original CDF is not modified.
SkeletonCDF

[]SkeletonCDF was previously named CDFskeleton. Reads a specially formatted text file (called a skeleton table) and creates a skeleton CDF. A skeleton CDF is complete except for record-variant data.

SkeletonTable
Reads a CDF and produces a specially formatted text file called a skeleton table. The skeleton table may be modified and then input to SkeletonCDF to create a skeleton CDF.
CDFinquire
Displays the version of your CDF distribution and the default toolkit qualifiers.
CDFstats
Produces a report containing various statistics about the variables in a CDF.
CDFcompare
Reports the differences between two CDFs.
CDFdir
Produces a directory listing of a CDF's files. For a multi-file CDF the variable files are listed in ascending numerical order.
