DB2 Multi-Row Fetch/Insert - COBOL Programming Modell

Customer addressed to IBM that the use of DB2 Multi-Row Fetch/Insert is not well accepted by the developers since it increases the programming complexity a lot and is not ease to use in COBOL.

Initial discussions pointed to the already addressed "DCLGEN" requirement describe below, but this was not the complete story they are looking for. Customer is not using "DCLGEN" today and therefore the requirement might be important for other client .Customer has implemented their own self-written COBOL copybook generator integrated into their ASG Rochade and CA Endevor software management environment. You will find an example of a typical generated copybook below. Based on my little COBOL understanding this would already cover what you have in mind for the "DCLGEN" extension.

          10 TIMESTAMP-L-AEND OCCURS 60 TIMES  PIC X(26).

customer is looking for a solution which simplifies the programming. In the case when a simple SQL FETCH will be used in a program, programmers can use a single COBOL command ("MOVE(CORRESPONDING)") to move all rows into the LINKAGE structure to call another program. This function is used by many programs and simplifies the structure of the program as well as simplifies future changes since the program does not need to be changed when both structures changes in a consistent manner. With "Multi Row Fetch" there is no single COBOL command that can be used to copy/move a single column to the LINKAGE structure for a subroutine call or to call another program. Each row has to be moved separately which complicates the programming. Therefore, they requested that we provide a similar function to MOVE(CORRESPONDING), but for multi-dimensional COBOL copybooks/structures, e.g. MOVE(CORRESPONDING(n)) where n is the columns number to be moved into a single-dimensional LINKAGE structure.
