Q:HI friends accually ihave one problem plesase let me know the alternate code of this code. Related field description of code: Add a field, CALvsPRD, "Calendar Day Starts Before/After Production Day" to the parameter set WRKORDER which accepts values 'A' or 'B' o B = Calendar Day Starts Before Production Day o A = Calendar Day Starts After Production Day o Any other value indicates the production and calendar dates are always the same. code: Automatic Execution Of *INZSR Subroutine /Z01 * retrieves WRKORDER field values. /Z01 * Calculate default Production Date and return it to caller. /Z01 * Production date defaults to system date /Z01 C Eval P@Pdate = %DATE() /Z01 * unless Calendar date starts Before PDN(production) date and /Z01 * system time is before PDN Start Time then /Z01 * PDN date is yesterday. /Z01 C If W@CALvsPRD = 'B' and /Z01 C %TIME() < %TIME (W@Strtime) /Z01 C Eval P@Pdate -= %Day(1) /Z01 * unless Calendar date starts After PDN date and /Z01 * system time is *GE PDN(production) Start Time then /Z01 * PDN date is tomorrow. /Z01 C ElseIf W@CALvsPRD = 'A' and W@Strtime > *Zero and /Z01 C %TIME() >= %TIME (W@STrtime) /Z01 C Eval P@Pdate += %Day(1) /Z01 C EndIf /Z01 C Eval *InLr = *On

RETRIVING DELETED RECORDS :- I'm frequently asked how to retrieve deleted records from an unjournaled physical file when the deleted records have not yet been removed from the file. Utility UNDEL lets you undelete records in a physical file. This public domain program is available in CISC and RISC versions, and the complete source code is available for download at: UNDEL for AS/400 Save File (RISC): http://www.as400network.com/sharewarefiles/undelris.zip UNDEL for AS/400 Save File (CISC): http://www.as400network.com/sharewarefiles/undel.zip UNDEL for AS/400 Save File (Source code): http://www.as400network.com/sharewarefiles/undelsrc.zip The utility takes advantage of the fact that deleted records in physical files are only flagged as deleted, and the record data still exists until it is overwritten or the file is reorganized with a utility such as RGZPFM. UNDEL simply reads the deleted record, then reuses the record by writing over it with the new record (thus eliminating the flag for the deleted record). Some homegrown and commercial utilities copy the file containing undeleted records to a save file, then use a program to read the save file, which contains live and undeleted records, to a file to undelete the records. The UNDEL utility is superior to the SAVF technique because there's no need to copy the file to a save file, which is especially important for really large files. When run, UNDEL displays the physical file records in their unformatted, raw text form. You can either position the display to a given relative record number or use F19 or F20 to find the previous and next deleted record, respectively. The utility also includes online help, which is almost unheard of for free utilities. Other utilities include the ability to undelete records. You can use the RTVDLTRCD command in the old QUSRTOOL (no longer supported by IBM). QUSRTOOL is now a commercial product called TAA Productivity Tools ( http://www.taatool.com ). The free file editor WRKDBF has a built-in undelete capability ( http://www.wrkdbf.com ), and several commercial file editors can undelete records. For a complete list of file editors, go to http://www.sourcebook400.com, select "Programmer Tools" under "Product Category," then select "File Editors."

Q:Hi all,i want accurate answer with code using in built functions.please sent me code as soon as posible. I have program nmed PGM1 which '' RETRIEVE Current production date''should correctly default the production date for the user who is issuing raw materials to the manufacturing.The production date can be different from the celendra date. However, the program does not make the correct adjustment for all manufacturing plants. there is a parameter which determines the production start time e.g. 07:00 if the system time precedes this,the program subtracts one from the celendra day.This work fine when the celendar day starts after production day as it does in England,the system should be adding one to the celendar day during the overlap. unfortunately the program was desined to assumed the celendar day always starts before the production day. Change required in the program: Change the PROGRAM PGM1 to use the new parrameter to decide whether to add or subtract 1 from the celendar day when determining the production date.
