Features of the DATACOM interface
Here
are some of the features of the ULTIM language that apply to the processing of DATACOM databases. Some are shown in the example below.
- Ability to automatically convert parts or the whole DATACOM dictionary into an ULTIM dictionary.
- Ability to directly access the DATACOM dictionary (keyword: @DATACOM).
- Automatic management of the link protocols to the databases.
- Additional
keywords of the PROCESS statement to resume reading a table from
a particular occurrence, forward or backward (FIRST, LAST,
FOLLOWING or PRIOR).
- Ability
to read in key order or physical order, as well as to simultaneously read several tables of a same area.
- Ability to directly access a table occurrence by its key or its address (REC-ID).
- Access to the REC-ID of the processed occurrence, as well as to the return code of the operation.
