Can occur be coded in 01 level?

The table element definition (which includes the OCCURS clause) is subordinate to the group item that contains the table. The OCCURS clause cannot appear in a level-01 description.

How do you declare occurs in Cobol?

An index is declared with Occurs clause using INDEXED BY clause. The value of index can be changed using SET statement and PERFORM Varying option. 01 WS-TABLE. 05 WS-A PIC A(10) OCCURS 10 TIMES INDEXED BY I.

Where can we specify occurs clause in Cobol?

The OCCURS clause specifies tables where elements can be referred by indexing or subscripting. The OCCURS clause cannot be specified with level number of 01, 66, 77 or 88 and redefined data item. Each OCCURS clause specified is called as a dimension and up to 7 dimensions can be specified in a table.

Where can we specify occurs clause?

The OCCURS clause can be specified for external or internal floating-point data items. The KEY clause must not be specified for a data item of class object. The Format 3 OCCURS clause must be specified in a data description entry at the 01 level.

What is occurs depending on clause in Cobol?

The COBOL OCCURS … DEPENDING ON clause defines a repeating data element whose number of occurrences is determined by a numeric item. The Plug-in converts this type of element to a repeating element in the XSD.

How exactly does binary code work? - José Américo N L F de Freitas

Why we use occurs in COBOL?

COBOL - Occurs Clause. OCCURS clause is used to define a table. OCCURS clause indicates the repetition of data name definition. OCCURS clause specifies tables whose elements can be referred to by indexing or subscripting.

Can COBOL display index value?

Re: how to display the value of the index variable in cobol

Yes, we can. Simply set some ws variable to the index and display that. Hope this helps, d.

What are level numbers in COBOL?

A level-number is a one-digit or two-digit integer between 01 and 49, or one of three special level-numbers: 66, 77, or 88. The following level-numbers are used to structure records: 01. This level-number specifies the record itself, and is the most inclusive level-number possible.

What is 88 level used for in COBOL?

Level 88s are used to assign names to values at execution time. Thus, a condition-name is not the name of an item, but rather the name of a value. A level 88 doesn't reserve any storage area. Each level 88 must be associated with a data item and must immediately follow that item in the Data Division.

How do you use redefines in COBOL example?

Redefines clause is used to define a storage with different data description. If one or more data items are not used simultaneously, then the same storage can be utilized for another data item. So the same storage can be referred with different data items.

What is Ssrange and Nossrange in COBOL?

SSRANGE is a compiler option that handles the array overflow. SSRANGE also needs to be specified in COBOL programing language. These help in finding the subscript out of range. NOSSRANGE is used for performance-sensitive applications.

What is Comp 3 variables COBOL?

(also called "Computational-3", "Packed Decimal", or "Packed") COBOL Comp-3 is a binary field type that puts ("packs") two digits into each byte, using a notation called Binary Coded Decimal, or BCD. This halves the storage requirements compared to a character, or COBOL "display", field.

What is file status 92 in COBOL?

The 92 file status code (LOGIC ERROR) indicates you're attempting to read a NEXT record without having established a current record to read the next record after.

What is static and dynamic call in COBOL?

Static Call occurs when a program is compiled with the NODYNAM compiler option. A static called program is loaded into storage at compile time. Dynamic Call occurs when a program is compiled with the DYNAM and NODLL compiler option. A dynamic called program is loaded into storage at runtime.

What is the difference between subscript and index?

Subscript refers to the array occurrence while index is the displacement (in no of bytes) from the beginning of the array. An index can only be modified using PERFORM, SEARCH & SET. Subscript refers to the array occurrence while index is the displacement (in no of bytes) from the beginning of the array.

What is the maximum length of PARM parameter in JCL?

The maximum length for the PARM variable is 100 characters, which might cause problems if you use custom directory names.

What is the difference between 01 and 77 level in COBOL?

The element in 77 cannot be subdivided or cannot have a group of subelements . This is to indicate the variable declared in 77 is an elementary(some thing for special purpose) and should not be subdivided . Level 01 can be elementary item or a part of a group item.

What is 77 level used for in COBOL?

Level 77 is a special level number in COBOL which is used to declare independent data items; they are not subdivisions of other data items and are not subdivided themselves. In earlier days there were differences in storage and processing of level 77 and level 01 elementary data items.

What is 66 level number in COBOL?

The 66 level assigns an alternate name to a field or group. It doesn't add a new field to the record, it just assigns an alternate name to an existing field. You must use the level number 66 for data description entries that contain the RENAMES clause.

Which is the lowest level number in COBOL?

What is level number?

The level-number specifies the hierarchy of data within a record, and identifies special-purpose data entries. A level-number begins a data description entry, a renamed or redefined item, or a condition-name entry.

What is 88 level number?

88 level number in COBOL is one of the most used declarations in mainframes development and it is considered as a special level number which is used to improve the readability of COBOL programs. As it gives a name to a condition, it is also called as 'Condition Names'.

Which is better index or subscript in COBOL?

Using indexes to address a table is more efficient than using subscripts since the index already contains the displacement from the start of the table and does not have to be calculated at run time.

Which is faster index or subscript?

Subscript is slow in accessing table data item. Index is faster in accessing table data item. Subscript can initialize by using MOVE statement.

Why index is faster than subscript in COBOL?

Indexes are more efficient than subscripts since they represent an offset into the array directly rather than having to be converted from an occurrence number to an offset.
