If you want to see COMP-3 values in sequential file since it is stored in decimal form, You need to use HEX ON commmand to see COMP-3 values, When you use this command it will show two lines per each record. You need to read the comp-3 value from left, top to bottom (in two lines) and then move to second character read top to bottom. For Example :

Each byte has two nibbles, and each nibble is indicated by a hexadecimal digit. COBOL comp variables speed up your execution time and save your storage space. Numerical calculations need your skill in dealing with COBOL comp-3 variables. The example below helps you how to use the Comp-3 variables in your COBOL program. How to MOVE comp-3 value to Numeric in COBOL COMP-3 enables the computer to store two digits in each storage position, except for the rightmost position, which holds the sign. The sign is stored separately as the rightmost half-a-byte regardless of whether S is specified in the PIC or not.

COMP-1 and COMP-2 are supposed to be floating point single precision and double precision, respectively. COMP-3 is the equivalent of PACKED DECIMAL. COMP-4 is the equivalent of BINARY. binary (comp or comp-4) BINARY data and synonyms COMP and COMP-4 are the two's complement data representation in COBOL.

Mar 10, 2012 · COMP-2 items are 8 bytes long. COMPUTATIONAL-3 or COMP-3 (internal decimal) This is the equivalent of PACKED-DECIMAL. COMPUTATIONAL-4 or COMP-4 (binary) This is the equivalent of BINARY. COMPUTATIONAL-5 or COMP-5 (native binary) These data items are represented in storage as binary data.

This is especially important in systems that process large volumes of financial transactions/amounts (e.g. banking, credit cards, etc.). USAGE IS COMP-3 Field A packed decimal representation stores two decimal digits in one byte. A packed decimal representation stores decimal digits in each "nibble" of a byte.

25 Jul 2020 Hi, I've to read a file which was transferred from Mainframe systems in Binary format. This file contains packed decimal(COMP-3) data.

Data length will be dependent on what you specify to be n in COMP-n (but n is not the length).

01 DETAIL-LINE. 05 WS-DATE PIC 9(08) VALUE 20181119. 05 FILLER PIC X(01). 05 WS-PREMIUM PIC S9(05)V9(02) comp-3. 05 filler pic x value '$'.

COMP-3 data stored in memory higher to lower in the size of nibble (4 bits). i.e. cobolでは、ワークの定義時に「comp-3」をつけることでパック10進数形式になります。・通常の定義の場合03 num pic s9(3). ・パック10進数で定義する場合03 num pic s9(3) comp-3.

Common Business-Oriented Language (COBOL) is a programming language similar to English that is widely used to develop business-oriented applications in the a 8.1.3 COMP-6/COMPUTATIONAL-6 Data. The RM/COBOL system holds COMP-6 data in a similar format to COMP-3 data, except there is no sign half-byte. If a sign is indicated in the picture clause it is ignored and has no effect. The value held is always positive. Consider the following examples: COMP-3 é um campo que coloca dois dígitos em cada byte, usando uma notação chamada Binary Coded Decimal, ou BCD. COMP-3 é um tipo de dado comum, mesmo fora do COBOL, e é bastante normal em plataformas - isto é, não é dependente do sistema operacional, língua, ou CPU. 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. COMP-3 stores the data in the BCD (Binary Coded Decimal)format.

binary (comp or comp-4) BINARY data and synonyms COMP and COMP-4 are the two's complement data representation in COBOL. BINARY data is declared with a PICTURE clause as with internal or external decimal data but the underlying data representation is as a halfword (2 bytes), a fullword (4 bytes) or a doubleword (8 bytes). From my research: Comp variables are used as counters and should be integers. Comp-3 variables are used for numeric data like amounts and decimal points are allowed. Dec 16, 2015 · COBOL comp variables speed up your execution time and save your storage space. Numerical calculations need your skill in dealing with COBOL comp-3 variables. The example below helps you how to use the Comp-3 variables in your COBOL program.

COMPUTATIONAL-3 or COMP-3 (internal decimal) For VS COBOL II, this is the equivalent of PACKED-DECIMAL. COMPUTATIONAL-4 or COMP-4 (binary) For VS COBOL II …

COMP-2 USAGE. Same as COMP-1 except that data represented internally in two words. Increases precision of the data. Picture clause cannot be specified. COMP-3 USAGE.

COMPUTATIONAL-5 or COMP-5 (native binary) These data items are represented in storage as binary data. The data items can contain values up to the capacity of the native binary representation (2, 4, or 8 bytes), rather than being limited to the value implied by the number of nines in the picture for the item (as is the case for USAGE BINARY data).

It could be signed or unsigned.

COMP Data is stored as pure binary format. The PIC clause of COMP data item should not contain other than 9 or S. Depending on the size of data item, data is stored either in Half-word (2 bytes) or full-word (4 bytes). 9(1) – 9(4) occupies 2 bytes 9(5) – 9(9) occupies 4 bytes S9(10)… Point 1) Comp-3 is used to avoid rounding issues that occur when binary numbers are used to represent decimal fractions. This is especially important in systems that process large volumes of financial transactions/amounts (e.g. banking, credit cards, etc.). USAGE IS COMP-3 Field A packed decimal representation stores two decimal digits in one byte.
