Each digit occupies 1/2 bite of memory, so this declaration is useful and it conserves the memory. For example, on main frame the memory word size is 4 bytes. This means that each word will start from an address divisible by 4. If my first variable is x(3) and next one is S9(4) COMP, then if you do not specify the SYNC clause, S9(4) COMP will start from byte 3 ( assuming that it starts from 0). 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.

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. 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.

The following shows the COBOL group definition of the data structure that contains the three numeric fields. This data

In all versions of COBOL, fractional numbers, except for COMP-1 and COMP-2, are processed as "fixed point" (an old FORTRAN term). This means that they are processed internally as integers and the compiler keeps track of the decimal point. I have tried the following on IBM mainframe COBOL, and got these results. 01 DETAIL-LINE.

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. How to MOVE comp-3 value to Numeric in COBOL Hi All, I would like to know how to calculate the Pic size of a COMP-3 and COMP variables.

COMP-3 will store the Comp-3 stores data in a BCD -- binary coded decimal -- format with the sign after the least significant digit. Comp-3 is so common that we have written a separate 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 COMPUTATIONAL-3 or COMP-3 (internal decimal): This is the equivalent of truncation occurs at the binary field size rather than at the COBOL picture size COMP-3/COMPUTATIONAL-3 Data. The RM/COBOL system represents COMP-3 data in packed decimal format with the least significant half-byte holding the 6.2 COMP-3/COMPUTATIONAL-3 Data. The RM/COBOL system represents COMP-3 data in packed decimal format with the least significant half-byte holding COMP-3 is 8 bytes. · Comp-3 is used for Packed Decimal values it allows S 9 V mostly it is useful for Decimal Calculation Values. · COMP-3 stores the data in the The following shows the COBOL group definition of the data structure that contains the three numeric fields.

Dec 16, 2015 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 … 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). Oct 03, 2016 COBOL Programming: I know the difference between a comp and and comp-3 variable. Could some1 please tell me in what all scenarios the usage comp Mar 10, 2012 Feb 18, 2003 By default, a BINARY data item is identical to a COMP-4 data item. The compile-time option "-D5" treats BINARY data items as COMP-5 items instead.

Several data fields are comp-3 (s9(13) v99). These compress data fields are not readable under Excel 9 Mar 2015 COMP2 : will store the data in 8 bytes, in Hexadecimal form and results more precise value. COMP3 : It is a packed decimal usage and which 25 Oct 2008 Mainframe COBOL style copybooks and COMP/Packed Decimals. I haven't DATA and convert the COMP and COMP-3 fields.

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 Hi All, I would like to know how to calculate the Pic size of a COMP-3 and COMP variables. My requirement is in my COBOL program one variable is declared as S9(9)V99 COMP-3.Now i would like to declare an equivalent alpha numeric for the COMP-3 variable. wat is the Pic size of alpha numeric ( X(??)) variable. Dec 09, 2017 · COMP-3. COMP-3 enables the computer to store two digits in each storage position, except for the rightmost position, which holds the sign.

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.

Greetings, I have a PIC 9(12)v99 COMP-3 variable and want to convert it to a decimal PIC 9(12)V99. I read that the true value of this comp-3 would be (12 +2 +1)/2 = 7,5 (8 rounded up), tried that but to no avail. Also tried a simple move from one to another but when i write my converted file (a text

The sign ½ byte values are C = signed positive D = signed negative F = unsigned (non COBOL). S9 (6)V9 (3) COMP-3 VALUE 123.45. Length is calculated as ROUND UP [ (9 + 1) / 2] = 5 bytes Computational clause is used to describe type of storage used in COBOL. It is used for 3 ways: COMP-1, COMP-2 and COMP-3. The most common form of computational is COMP-3. It frequently is just called "COMP" by programmers. Sep 16, 2013 · cobol – sign stored in comp, comp-3 and display formats sign is stored in different formats as shown below.
