HDS objects are created, accessed, modified and deleted in programs by means of calls to HDS routines. The routine names have the following structure:
<pkg>_<func><qual>
where <pkg>
is the "package name", <func>
represents
the function performed by the routine and <qual>
is a qualifier
which is used to identify different versions of the GET, MAP, MOD, NEW
and PUT routines.
