What is Comp-5 sync in COBOL?

When numeric data is moved or stored into a COMP-5 item, truncation occurs at the binary field size rather than at the COBOL picture size limit. When a COMP-5 item is referenced, the full binary field size is used in the operation.

What is the range of S99V99 Comp-5?

For example, a data item described with PICTURE S99V99 COMP-5 is represented in storage as a binary halfword, and supports a range of values from -327.68 to +327.67.

How comp values are stored?

In COMP usage Data is stored as Pure Binary format internally. Depending on the size of the data item, it can be stored either in a half-word (2 bytes with range 32,768 to +32767) or full- word (4 bytes with range 2,147,483,648 to 2,147,483,647).

What is Comp-3 variables COBOL?

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 difference between comp and comp3?

Comp is a binary usage, while comp-3 indicates packed decimal. The other common usages are binary and display. Display is the default. 3/28/00 Dave Herrmann: ‘I was reading your FAQ on Cobol, as an fyi Comp is defined as the fastest/preferred numeric data type for the machine it runs on.

Can we display Comp-3 variables COBOL?

In the below file, the last 2 Bytes are COMP-3 Data. You read the Hexa-decimal value in a top-down fashion. 3. You may also DISPLAY this in COBOL, by first MOVE’ing the data to a Numeric-Edited DISPLAY Format Variable.

What’s the difference between Comp 4 and Comp 5 in COBOL?

comp-4 is the VOS COBOL short integer data format. comp-5 is the VOS COBOL long integer data format. comp-6 is the VOS COBOL scaled fixed-point data format. comp-4 is fixed-point binary data with 15-bit precision, word-aligned, and stored in two bytes. The scaling factor is zero. Values are stored in two’s complement form.

How is a data item represented in COBOL?

Data item is similar to Long or Double and is represented as double precision floating point number. Internally, data is stored in hexadecimal format. COMP-2 does not specify PIC clause. Here 2 word is equal to 8 bytes. Data item is stored in packed decimal format.

What kind of data format does Vos COBOL use?

VOS COBOL supports short and long fixed-point binary integer data formats described in this section, as well as a decimal scaled binary data format. comp-4 is the VOS COBOL short integer data format. comp-5 is the VOS COBOL long integer data format.

When to use the rename clause in COBOL?

Renames clause is used to give different names to existing data items. It is used to re-group the data names and give a new name to them. The new data names can rename across groups or elementary items. Level number 66 is reserved for renames. Renaming is possible at same level only.
