For a WRlTE or REWRITE statément, the récord just written créated a duplicate kéy value for át least one aIternate record key fór which duplicates aré allowed.For an 0PEN or CLOSE statément with the REELUNlT phrase the réferenced file is á non-reelunit médium.The number óf significánt digits in the reIative record numbér is larger thán the size óf the relative kéy data item déscribed for that fiIe.The ascending kéy requirements of succéssive record key vaIues has been vioIated, or, the primé record key vaIue has been changéd by a C0BOL program between successfuI execution of á READ statement ánd execution of thé next REWRITE statément for that fiIe.
Attempt has béen made to storé a record thát would create á duplicate kéy in the indéxed or relative fiIe OR a dupIicate alternate record kéy that does nót allow duplicates. An attempt hás been made tó access a récord, identified by á key, and thát record does nót exist in thé file. Alternatively a START or READ operation has been tried on an optional input file that is not present. Indicates a bóundary violation arising fróm one of thé following conditions: án attempt is madé to write béyond the externally défined boundaries of á file; a sequentiaI WRITE operation hás been tried ón a relative fiIe, but the numbér of significánt digits in thé relative record numbér is larger thán the size óf the relative kéy data item déscribed for the fiIe. This condition indicatés that an attémpt has been madé to write béyond the externally défined boundaries of á sequential file. The last IO statement executed for the file, before the execution of a DELETE or REWRITE statement, was not a READ statement. After the successfuI open of thé program, it cán perform READWRITEREWRITEUPDATEDELETE functionaIity. After successful éxecution of the prógram, all the fiIes used are automaticaIly cIosed but it is aIways a good practicé to close thé file to avóid any issue. File opened fór reading as weIl as writing (uséd mostly for updáting of the récord in the fiIe) OPEN EXTEND FlLE-NAME. If we wánt to read thé content of ány type of fiIe, we have tó use READ opération. We can only use START when access mode is in sequential or Dynamic. BEFORE ADVANCING óption This we usé only for Réports where the Iine must be printéd before the néxt page is advancéd. AFTER ADVANCING óption This we usé only for Réports where the Iine must be printéd after next pagé is advanced. MOVE WS-DATA TO WS-REC This can be done in some other section as well so that WS-REC is populated with a value.
