! The following example code shows how to create groups
|
||
|
|
! using absolute and relative names. It creates three groups:
|
||
|
|
! the first two groups are created using the file identifier and
|
||
|
|
! the group absolute names, and the third group is created using
|
||
|
|
! a group identifier and the name relative to the specified group.
|
||
|
|
!
|
||
|
|
! This example is used in the HDF5 Tutorial.
