ODO's are useful when using SEARCH/SEARCH ALL on variable sized tables and some other COBOL features. The new code you write is just the specifics of the next task. IBM Mainframe Forum. 05 WS-TEMP-CNT 1. The convention I have seen is typically to hard-code it to match the occurrences in working storage. index-name - The name of the index associated with the table. But I think this SEARCH is having some disadvantages when used for searching 2-d arrays. cbl example from the link where records are included/excluded based on having a specific gender code. About; COBOL VSAM/QSAM file status codes; RSS Feed. En tant qu'enregistrements à trier, Your original code nearly works. 4 min read. (FILE SECTION or LINKAGE SECTION are exception).

Sorting is required for sequential processing as the files need to be sorted in ascending/descending order. Arrays may be declared for elementary or group data items at levels 02-49.

It sorts table elements according to specified table keys. 1) Last updated on JANUARY 26, 2024. if it is not a host variable for db2, then it is a COBOL internal Table : Back to top: UmeySan Active Member Joined: 22 Aug 2006 Posts: 771 Location: Germany: Posted: Thu Jan 27, 2011 4:56 pm @ rgupta71 Sir, why not using a separate Sort which would RELEASE each item of the COBOL Internal Table to SORT and then repopulate the COBOL Internal Table with the RETURN statement results. I do not believe there is a standard method for doing this in COBOL. It can be used for both sorted The SORT statement creates a sort file by executing input procedures or by transferring records from another file, sorts the records in the sort file on a set of specified keys, and in the final phase of the sort operation, makes available each record from the sort file, in sorted order to some output procedures or to an output file. You can add, delete COBOL logic for de-normalized file to Normalized table. Therefore, we don't have "null strings" (a string of length one Consult the Enterprise COBOL Programming Guide, Chapter 12 I think, and see how to use SORT-RETURN to confirm that the SORT completed successfully. I have this table: 01 TB-1 OCCURS 10 INDEXED X1. Why I am stressing to use cobol internal sort is because the NACHA formated file h.
