Creation of standard directories

Before storing any data, the user has to create a directory with all specifications of the key vector. The routine CDMDIR permits the creation of HEPDB standard directories, with any number of additional user keys. The option 'P' (partitioned) can be used to create a partitioned directory. The dictionary directory is automatically updated upon creation of a new directory. In case the directories at the intermediate nodes do not exist, CDMDIR will create them automatically with 9 integer keys. Even if a directory is created as a non-partitioned directory it may be converted at any time using the routine CDPART.
