This flowchart depicts the logical processing flow for the standard ADD/DUP (Add/Duplicate) Function in a MAGEC-generated MMP (online program). It handles both new record addition and duplicate key detection. It shows the main paths: initialization, key normalization, read to check for duplicates, multi-stage editing, calculation, add to database, error handling, and screen output. Key concepts: Pseudo-conversational processing, insertion points (%XXXXX), continuation vs. new transaction modes, duplicate key checking, and business rule processing. The business rule (RULPROC) pertaining to any of the MMP's elements from its primary Data Class will be inserted immediately after the %CALC logic. It could set the ERROR-FOUND condition causing the program to take the error path, bypassing the add to the database. %PREINIT BA100-INIT-STORAGE %INIT AAM200-MAINTENANCE-MAINLINE %PFKEYM BA210-MAINT-SCREEN %INITATB BA400-NORMALIZE-MAINT-KEY %NORMKEY %REDKY %JOIN %JOIN %EDIT BB500-SCREEN-EDIT-2 %EDIT2 BB600-BUILD-REC %ADDINIT BB600-BUILD-REC (continued) %CALC AAM710-ADD-TO-DATABASE %ADDIT %GOODADD AA800-SEND-SCREEN / %SNDSCRN (GO TO TOP OF SEE FUNCTION) %COMP AA800-SEND-SCREEN %BLNKSCR AA800-SEND-SCREEN %SNDSCRN AA900-GOBACK %GOBACK %UPDERR (AAM751-UPDERR) AA800-SEND-SCREEN Processing Diagrams - Figure 06 ADD/DUP Function Insertion Points Reference Master Index (search for %ADDINIT, %ADDIT, %GOODADD, etc.)
