Datum object characteristics

The datget and datset commands provide a keyed-list interface to datum object characteristics. If datget is called with only a datum handle, then it returns the characteristic keys that are available.

For example:

Input: datcreate 17760704 dt
Output: datum2
Input: datget datum2
Output: TYPE VALUE

Use these keys to query the characteristics.

For example:

Input: datget datum2 TYPE
Output: dt
Input: datget datum2 VALUE
Output: 17760704

Modify the datum through datset.
