What does Z mean in COBOL?

What does Z mean in COBOL?

As shown in the chart, the Z suppresses leading zeros by turning them to a space. The number 0024 would print as space space 24. The Z only suppresses leading zeros, embedded zeros such as the zero in the number 2005 are not suppressed. The decimal point means print an actual decimal point in this space.

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.

How many bytes is S9 4 comp?

2 bytes
COMPUTATIONAL-5 or COMP-5 (native binary)

Picture Storage representation
S9(1) through S9(4) Binary halfword (2 bytes)
S9(5) through S9(9) Binary fullword (4 bytes)
S9(10) through S9(18) Binary doubleword (8 bytes)
9(1) through 9(4) Binary halfword (2 bytes)

What is comp COMP1 COMP2 COMP3 in COBOL?

COMP1: will store data in 4 bytes, floating point form and result the rounded value. 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 occupies one digit/ half byte of the storage space.

What PIC 9v99 means?

PICTURE 9v99 is a three position Numeric field with an implied or assumed decimal point after the first position; the v means an implied decimal point.

Is COMP or COMP-3 better?

Comp-3 = Packed-Decimal is faster, because the z/Architecture, and also previous architectureres beginning with S/360, has built in instructions to directly manipulate Packed-Decimal data, e.g AP (Add packed).

What is difference between Comp and Comp-3?

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.

How many digits can a S9 4 Comp hold?

You can have values in the range -9999 to +9999 in a S9(4) COMP-3 (packed decimal) field.

What is the difference between COMP 1 and COMP 2?

COMP-1 refers to short (single-precision) floating-point format, and COMP-2 refers to long (double-precision) floating-point format, which occupy 4 and 8 bytes of storage, respectively. The leftmost bit contains the sign; the next seven bits contain the exponent; the remaining 3 or 7 bytes contain the mantissa.

What is the difference between PIC 9.99 and PIC 9v99?

What is the difference between PIC 9.99 and PIC9v99? PIC 9.99 is a four position field that actually contains a decimal point where as PIC 9v99 is three position numeric field with assumed decimal position.

Can I declare occurs in 01 level?

The table element definition (which includes the OCCURS clause) is subordinate to the group item that contains the table. The OCCURS clause cannot appear in a level-01 description.

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. 01 A1 PIC S9(4) COMP-3 VALUE 1234.

Which is better comp or COMP3 in COBOL?

How do I convert numeric to COMP3 in Cobol?

Assuming that the PIC X variable does have nothing but numeric digits, your best bet is a two-step move: move the PIC X to USAGE DISPLAY variable, then move the USAGE DISPLAY variable to the COMP-3 variable.
