LOC / SCN / FND Function — Browse and selection logic with continuation and new transaction modes. The %SELECT insertion point sets a flag to process, bypass, or simulate EOF for each item read for any LOC, SCN, or FND function. The SCN and FND functions also perform further selection matching afterwards. Entry into the LOC / SCN / FND Function. Check function code and perform pre-initialization processing. Earliest developer intercept point — runs for every transaction and every function.

Tests for cursor selection, continuation mode, new transaction mode, and blank key. AAL200-BROWSE-MAINLINE insert_main.htm#insert001027MAIN First 10-bytes of Mask Area give Mask ID, Cursor position, Entry key detection (ENTER, CLEAR, PF1, PA1, etc.). TWA-MSK-AREA https://www.magec.com/DOC/genmmp_main.htm#genmmp004025 MAIN AAL200-BROWSE-MAINLINE Tests whether the operator positioned the cursor on a valid record and pressed Enter to select it. If yes, bypasses the full browse read loop. genmmp_main.htm#genmmp004025MAIN route directly to AA900-GOBACK to FTH-FUNCT to SEE/CHG for the selected record. genmmp_main.htm#genmmp004025MAIN route directly to AA800-SEND-SCREEN. route directly to AA800-SEND-SCREEN. route directly to AA900-GOBACK to FTH-FUNCT to SEE/CHG for the selected record. route directly to AA900-GOBACK to FTH-FUNCT to SEE/CHG for the selected record. Determines the processing mode: Continuation Mode (operator paged or scrolled), New Transaction Mode (fresh entry), or Test Key = Space (blank key entered). All three routes converge at BA300-NORMALIZE-KEY. insert_main.htm#insert001025MAIN Determines the processing mode: Continuation Mode (operator paged or scrolled), New Transaction Mode (fresh entry), or Test Key = Space (blank key entered). All three routes converge at BA300-NORMALIZE-KEY. insert_main.htm#insert001025MAIN Normalize the browse key entered by the operator — reformat and validate it for use as the starting position key. BA300-NORMALIZE-KEY insert_main.htm#insert001025MAIN Tests whether a key error was detected during normalization. If a key error is found, bypass all file reading and route directly to SEND-SCREEN. insert_main.htm#insert001025MAIN Tests whether a key error was detected during normalization. If a key error is found, bypass all file reading and route directly to SEND-SCREEN. insert_main.htm#insert001025MAIN Set the file starting position for the browse read loop using the normalized key. insert_main.htm#insert001021 MAIN AAL410-SET-STARTING-POSITION Read the next sequential record from the file. This is the top of the browse read loop — control returns here from %SELECT (bypass/reject) and from CA800 (not EOF and screen not full). AAL430-READ-NEXT-RECORD insert_main.htm#insert001033MAIN Read the next sequential record from the file. This is the top of the browse read loop — control returns here from %SELECT (bypass/reject) and from CA800 (not EOF and screen not full). insert_main.htm#insert001033 MAIN AAL430-READ-NEXT-RECORD Perform logical join — secondary files or derived fields joined to the primary record. EOF or NOT FOUND at this point routes to SEND-SCREEN. insert_main.htm#insert001018 MAIN JA100-LOGICAL-JOIN Tests whether end-of-file or record-not-found was indicated by the join. If either condition is true, the browse list is complete — route to SEND-SCREEN. route to SEND-SCREEN. Move data to work area and apply selection logic. %SELECT sets a flag: PROCESS (include this record), BYPASS (skip — loop back to read next), or REJECT (skip — loop back to read next). SCN and FND functions apply additional matching here. insert_main.htm#insert001067 MAIN CA700-MOVE-TO-WORK-AREA Build the display line for this record . insert_main.htm#insert001023 MAIN CA700-MOVE-TO-WORK-AREA Evaluates the %SELECT flag. BYPASS or REJECT loop back to read the next record. PROCESS (no bypass) continues to build the screen key entry. Evaluates the %SELECT flag. BYPASS or REJECT loop back to read the next record. PROCESS (no bypass) continues to build the screen key entry. Build the screen key entry for this record and add it to the browse list to be used if operator cursor-selects this record. After building, tests whether the screen is full or EOF was reached. insert_main.htm#insert001038 MAIN CA800-BUILD-SKEY Up to 16 keys of items found/listed are saved for a 'Short List' that the operator can display by hitting PF24. Cursor selecting from that list fetches the full-screen SEE Function for the selected item. Short Lists https://www.magec.com/DOC/user_main.htm#user022000 MAIN Determines next action after building a screen entry. If screen is full or EOF, the list is ready — route to SEND-SCREEN. If neither, loop back to read the next record. Determines next action after building a screen entry. If screen is full or EOF, the list is ready — route to SEND-SCREEN. If neither, loop back to read the next record. Send the resulting browse screen back to the operator. All paths converge here: cursor selection, key error, EOF/not-found, screen full, and EOF after SKEYBLD. insert_main.htm#insert001039 MAIN AA800-SEND-SCREEN Return control to the caller (GOBACK). Absolutely the last point in the logical flow. insert_main.htm#insert001012 MAIN AA900-GOBACK LOC / SCN / FND Function processing complete. Figure 02 - LOC / SCN / FND Function
