How do you move Comp three variables to alphanumeric in COBOL?
You cannot move a COMP-3 variable to alphanumeric directly. It will not give a SOC7 error but will you give you a return code 12 stating that comp-3 and alphanumeric variables did not follow the move compatibility rule. 01 A1 PIC S9(4) COMP-3 VALUE 1234.
How do I convert comp to numeric in COBOL?
RE: moving COMP value to numeric value
- 01 val1-display PIC 99.99999. Very Important! I am presuming that you have remembered to initialize. the val1 by coding :-
- MOVE 0.324 TO VAL1. So now, add.
- MOVE VAL1 TO VAL1-DISPLAY. DISPLAY ‘VAL1-DISPLAY=>’ VAL1-DISPLAY. Let us know how you go.
Can we move numeric to alphanumeric in COBOL?
You Can’t move alphanumeric/non-numeric to numeric.
Can we move packed decimal to alphanumeric in COBOL?
A packed decimal field can be treated as alphanumeric; as long as Jithucse doesn’t expect to use the packed decimal field as a number there’s no problem. That is correct Robert. Group MOVE in COBOL will always be considered as Alphanumeric. Getting the value directly in to the Group variable will not cause any error.
Can we move Comp-3 to comp?
1. it possible to move a comp-3 field to a comp field or display field and vice versa.. 2. it possible to redefine a field with comp-3 status to a comp status.
Can we move alphanumeric to comp3 in COBOL?
Re: Alphanumeric to COMP-3 data movement In comp-3 data representation is in packed decimal and in alphanum data is stored in ascii form so bcuz of data incompatibility Alphanumeric to COMP-3 data movement is not possible.
Can Comp-3 be converted to numeric?
The internal format for a PIC S9(03) COMP-3 variable with a value of +059 is X’059C’ — note that this is only two bytes, but that’s the way COMP-3 variables are stored. There is absolutely no way you can use a REDEFINE into a USAGE DISPLAY variable that will allow this value to be processed as a numeric value.
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 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 Comp-3 variables Cobol?
How are Comp-3 values stored?
COMP-3 can have a value not exceeding 18 decimal digits. COMP-3 data stored in memory higher to lower in the size of nibble (4 bits). i.e. The upper nibble stores the most significant digit and lower nibble stores the next digit and the upper nibble stores the next digit etc.
Can we redefine Comp-3 Variable?
Hello Srikar, There is no way to use only redefines and get what you want. . . To get what you want, create a 9(13) field in ws and move EMP-NBR-1 to it. Redefine the 9(13) field with 2 other fields – the first 9(10) and the second 9(3).
How do you display the Comp-3 in readable format?
1. In case the COMP-3 Data, that you want to see is the data in a Mainframe File, and you would like to see the contents on TSO/ISPF, you can turn the HEX ON on the Command Line. In the below file, the last 2 Bytes are COMP-3 Data. You read the Hexa-decimal value in a top-down fashion.
How do you read Comp-3?
If an item declared as COMP-3, the item appears in storage in packed decimal format. The right most half byte contains the sign value. COMP-3 data item contains any of the digits 0 through 9, a sign. COMP-3 can have a value not exceeding 18 decimal digits.
How is Comp-3 calculated?
To calculate the byte-length of a comp-3 field, start with the total number of digits and divide by 2 giving a result (discarding the remainder if any), then add 1 to the result. So, a field with “pic s9(6) comp-3” would take 4 bytes (6/2 +1).
Can we move alphanumeric to COMP3 in COBOL?
Why do we use comp-3 in 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 Comp and Comp-3 in COBOL?
COMP usage stores the data in half word or in full word, depending on the size of the data. COMP3 usage stores 1 digit in half byte (i.e. 4 bits) and a separate 1 bit is reserved for the sign, which is stored at the right side of the data.
Why do we use comp-3?
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 BCD(Binary Coded Decimal)format. It is used to avoid rounding issues that occur when binary numbers are used to represent decimal fractions.
