Index in cobol
19 avr. 2008 [Débutant] Les indices et les index. Bonsoir, J'apprends actuellement de façon autodidacte COBOL, et j'ai des incompréhensions concernant les Index in COBOL Table. Index. Displacement of an element from the start of the table is known as an index. An index is declared with OCCURS clause using INDEXED BY clause. Using SET and PERFORM varying option the value of an index can be changed. Index and Subscript in COBOL are the very important concepts. Both are used to reference an array or table element in COBOL programs. By knowing the basic differences between the two, one can code the programs efficiently in performance point of view. An index is a displacement of element from the start of the table. An index is declared with Occurs clause using INDEXED BY clause.

Setting an index to 2, will cause the compiler to correctly calculate the byte offset and point to the 2 nd element in the table. Likewise, setting an index up by one will move the index to the next element, regardless of the size of the element. The COBOL compiler translates it into a proper offset for you. XTEMP is not a COBOL data-item; it is not defined elsewhere in the DATA DIVISION. Its only use in the program is to serve as an index to the array TEMP. It can be used as a normal data item subscript when referencing an element of an array: COBOL STRING HANDLING - Learn Delimited by size and space in COBOL.
