How many bytes Comp-3 will take?

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).

How is data stored in Comp-3?

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.

What is Comp-3 variable in mainframe?

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.

How many bytes does Comp occupy?

COMP-1 takes 4 bytes of storage. COMP-2:This is same as COMP-1, except that the data is represented internally in two words. The advantage is that this increases the precision of the data, which means that more significant digits are available.

What is Comp and Comp-3 in COBOL?

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.

How many bytes S9 10 usage is COMP-3 will take?

9(01) – 9(04) : 16 bits (2 bytes) 9(05) – 9(09) : 32 bits (4 bytes) S9(10) – S9(18) : 64 bits (8 bytes)

How many bytes will S9 4 Comp-3 occupy?

It occupies 5 bytes.

How many bytes will a S9 10 Comp-3 field occupy?

5 bytes. Quote: There are 2 digits for each character position, except for the trailing character position, which is occupied by the low-order digit and the sign.

Can Comp-3 be converted to numeric?

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.

Can we move Comp-3 to comp?

Hi, 1. it possible to move a comp-3 field to a comp field or display field and vice versa..
