Loading of IMAGE Definitions
IMAGE Data Items
IMAGE Data Items
SDDBD will load the data items defined in the IMAGE database as element entity type in
the System Dictionary. The attributes initialized for each definition are:
IMAGE/V attribute System Dictionary attribute
item type element-type
sub-item length byte-length
sub-item count count
The byte-length value is derived from the sub-item length as follows:
In addition, the sensitivity and display-length attributes are also set. The sensitivity
attribute is set to the value specified in the IMAGE command. The display-length
attribute, which is used for display information on output, is derived from the Item Type
and Sub-item Length IMAGE information as follows:
Compatible and Incompatible Data Items. For data items, a conflicting entity is
defined as an entity which has an incompatible definition which already exists in the
dictionary. Hence, SKIP, REPLACE, TERMINATE, and NEW options are effective only for
the data items that have an incompatible definition in the dictionary.
On the other hand, if a compatible data item is found in the dictionary, the following
message is issued, and the old definition is automatically used:
Compatible definition for element ! used (SDWARN 2502)
For elements, a compatible definition is defined as an old definition with the same name
such that its values for those attributes specified in the COMPATIBILITY-LEVEL option
of the IMAGE command match those of the new definition.
