This stub is linked to the calling program, passes on the request to the IMS system, and returns the results and a status code. In any full-function IMS database, the smallest element that can be retrieved is a segment. Each segment is made up of fields, one of which, typically, will be a key field. The segments are arranged hierarchically in ...

TELON supported multiple database technologies, including IBM's VSAM, IMS/DB, DB2, plus Cullinet's IDMS. TELON is an application code generator that uses macros to generate COBOL, COBOL/II, or PL/I code that can run natively in the target environment without run-time proprietary code. Developers create screen designs in the TELON Design ...
If these applications needed to access shared resources they either used a Sysplex-exploiting datastore (such as IBM Db2 or IMS/DB) or concentrated, by function-shipping, the resource requests into singular-per-resource Resource Owing Regions (RORs) including File Owning Regions (FORs) for VSAM and CICS Data Tables, Queue Owning Regions (QORs ...
This numbering is generated by Natural during program creation. Line numbers used by the compiler and editors, and can have important logical functions in the programs. Comments can be included in two ways: Full-line comments are identified by a "*" or "**" prefix. Annotated code lines have a "/*" - everything to its right is a comment. Examples:
Some - can only reverse engineer the entire database at once and drops any user modifications to the diagram (can't "refresh" the diagram to match the database) Forward engineering - the ability to update the database schema with changes made to its entities and relationships via the ER diagram visual designer Yes - can update user-selected ...
