A variable may be deleted from a single-file CDF.
Deleting a variable also causes the deletion
of the corresponding attribute entries
for the variable. The disk space used by the variable definition, the
variable's data records, and the corresponding
attribute entries becomes available for
use as needed by the CDF library. Also, the variables which numerically
follow the variable being deleted are renumbered immediately. (Each
is decremented by one.)
Variables are deleted using the
<DELETE_,rVAR_>
and <DELETE_,zVAR_>
operations of the Internal Interface.
