Dec 15, 2008 · %EOF returns ‘1’ if the most recent read operation or write to a subfile ended in an end of file or beginning of file condition; otherwise, it returns ‘0’. ) eof The READC operation can be used only with an externally described WORKSTN file to obtain the next changed record in a subfile. But you don't check for end of file after the READE, so it would process the 'SGD' record. (REC1 is a record format C* name. An EOF condition also applies when end of file occurs. When %EOF returns '1', * the program will leave the loop. READP and READPE return %EOF=*ON if the beginning of file is reached. go4as400. Apr 21, 2015 · So, instead of checking any resulting indicator we simply use %EOF to check if the end of file is reached. com - A programming guide to learn AS400 Toggle navigation IBM i (AS400) Tutorial the file has end-of-file delay Normally, the comparison between the specified key and the actual key in the file is done by data management. %EOF built-in function example: DOU %EOF(MASTER) READ(N) REC1 IF %EOF(MASTER) A READE with the search-arg operand specified that immediately follows an OPEN operation or an EOF condition retrieves the first record in the file if the key of the record matches the search argument. If the file is read in a Do loop or a For group the last record read is locked. " When %EOF returns '1', the program * branches to the label BOF specified in the GOTO operation. C* C KEYFLD READEFILEA 55 NOT EQUAL C* C* The READE operation retrieves the next record of the type Ü READC (E) (Read Next Changed Record) · READC will cause our program to read subfile records that have been changed, keyed into, field exited. You can use the %Eof built-in with all read operations. The indicator is either set on (an EOF condition) or off every time the READ operation is performed. READE example is given below. Jun 28, 2007 · In order to do speed it up I nested my read loop in a subroutine and I just call the subroutine once for each key in question. The operations that set %EOF are: READ (Read a Record) %EOF built in function is used to detect end-of file, beginning of file, or subfile full conditions while performing a file operation similar to resulting indicator. The trouble is; using the wrong built in function can be easy to do and sometimes not easy to spot an obvious error. Mar 7, 2007 · Re: DOW with %EOF and CHAIN I thought i was going senile or something. We are on V5R4. Oct 7, 2009 · The modern generation of RPGLE %eof, %equal, %found %BIFS let us accurately and clearly handle native file IO. Oct 7, 2009 · Re: Difference between %EOF & Not %Found Copied from the RPG Reference: 1. (REC1 is a record * format name. * * The %EOF built-in function is set to return '1' if KEYFLD is * not equal to the key of the record read or if end of file * is encountered. If the operation is not successful, %EOF(filename) is not changed. * %EOF is set to return '1' if an end of file occurs on READ, * or if an end of file has occurred previously and the file * has not been repositioned. it says "You can specify an indicator in positions 75-76 to signal whether an end of file occurred on the READ operation. Convert RPG400 source to RPGLE; 0010. In some cases this is impossible, causing the comparison to be done using the hexadecimal collating sequence. That's because READE will return end-of-file when it hits a record whose keys don't match the key fields specified on the instruction. If you specify no file, %Eof checks the last file read for end-of-file. Chapter 22, built in functions, page 479 of the IBM rpg reference. Jun 9, 2021 · The READ at the end of the loop gets the 'SGD' record, and then the READE at the top of the loop attempts to get another record, but it would get end of file. Nov 9, 2014 · Re: Setll + read (reade) The fundimental problem is that the SETLL is being performed every time in the loop. READE reads the matching record for factor-1 and moves the pointer to the next record with the same matching criteria. READ, READC and READE return %EOF=*ON if the end of file is reached. The record-name operand is required and must be the name of a record format defined as a subfile by the SFILE keyword on the file description specifications. If the input file is coded for update any record that is read is locked until it is released, either by another read of the same file or by using the Unlock operation code, UNLOCK. "The following operations, if successful, set %EOF(filename) off. C READP FILEA C IF %EOF C GOTO BOF C ENDIF * * The READP operation reads the next prior record of the type * REC1 from an externally described file. Jul 15, 2015 · This is the extender I use the most with Read operations. 00 C If there are no more records it sets EOF *ON. ) C* C* The READE operation retrieves the next record from the file C* FILEA and compares its key to the search argument, KEYFLD. The second time it does not even successfully manage to read as it sees %EOF as on and skips right past the read. C* Indicator 55 is set on if KEYFLD is not equal to the key of C* the record read or if end of file is encountered. If the same matching criteria is not found then it foes to EOF. Hence, READC will detect these cases also. 835 it states regarding READ opcode but could not find answer specific to my query here with respect to setting the position on 'LO' and 'HI' places for READ operation on a keyed file. FXXFILE if e k disk D XX1 s 1A D X S 3s 0 inz /Free XX1 = 'O'; Setll (XX1: 11) XXFILE; Reade (XX1: 11) XXFILE; Dow not %eof; Eval x = X + 1; Reade (XX1: 11) XXFILE; Enddo; *inlr = *on; The READE operation retrieves the next sequential record from a full procedural file if the key of the record matches the search argument. * C KEYFLD READE FILEA * * The READE operation retrieves the next record of the type REC1 * from an externally described file and compares the key of the * record read to the search argument, KEYFLD. The operations that set %EOF . %EOF returns '1' if the most recent read operation or write to a subfile ended in an end of file or beginning of file condition; otherwise, it returns '0'. READP opcode example is given below. %EOF with no parameter is not changed by these operations. www. WRITE operation returns %EOF=*ON if the WRITE operation to a subfile detail record returned a subfile-full condition. If there are 4 records, it sets the file cursor at the first one, reads the first record and then repeats.

Oct 24, 2020 · READ, READC and READE return %EOF=*ON if the end of file is reached. If the key of the record does not match the search argument, an EOF condition occurs, and the record is not returned to the program. %EOF returns ‘1‘ if end-of file, beginning of file, or subfile full condition is found ; otherwise, it returns ‘0’. READ (Read a Record) READC (Read Next Changed Record) READE (Read Equal Key) READP (Read Prior Record) READPE (Read Prior Equal) The %Eof built-in function tests a specified file for end-of-file. · Even we not making any change in the record but we are keying in some value (by mistake) or pressing the field exit key, the record is supposed to be changed.
