Can we move zeros to Comp-3 Variable?

Can we move zeros to Comp-3 Variable?

When you move ZERO/ZEROS/ZEROES to a group level which contains elementary COMP-3 fields (in this example) 12-Bytes of Display-Numeric ZERO (X’F0′) is moved to all three fields, which will eventually cause a S0C7 Data Exception.

Can we move numeric to comp in Cobol?

Any numeric variable (USAGE DISPLAY, COMP, COMP-1, COMP-2, COMP-3, COMP-4, or COMP-5) can be moved to a COMP-3 variable with only truncation and overflow issues possible, depending upon the PICTURE clauses involved.

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..

Can we redefine Comp-3 Variable?

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).

What is Comp-3 variables 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.

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.

How do you define a table array in COBOL?

COBOL uses OCCURES clause to define a table/Array in the programming structure. OCCURES clause specifies the number that represents how many times the data item repeated in the table. There are two parts in the table/array i.e., first one is the table name and the second one is data item which repeats in the table.

What is usage display in COBOL?

USAGE IS DISPLAY The data item is stored in ASCII format and each character will take 1 byte. It is default usage and a data item is stored in a couple of contiguous bytes.

What is the difference between rename and redefine in COBOL?

REDEFINES VS RENAMES: RENAMES clause is used for regrouping elementary data items and gives one name to it. REDEFINES clause allows you to use different data descriptions entries to describe the same memory area.

How to move Pic X to comp-3 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. This will allow COBOL to handle the conversion between the PIC X internal storage format and the COMP-3 internal storage format.

What does a move statement mean in COBOL?

COBOL MOVE. MOVE statement is used to copy the literal or value of a data item (variable) to other data item (variable) in COBOL. MOVE statement does not mean moving the data from one variable to another variable. MOVE statement copies the value of a variable to another variable.

Can a numeric variable be moved to a comp-3 variable?

Your knowledge is WRONG. Any numeric variable (USAGE DISPLAY, COMP, COMP-1, COMP-2, COMP-3, COMP-4, or COMP-5) can be moved to a COMP-3 variable with only truncation and overflow issues possible, depending upon the PICTURE clauses involved. You generally cannot move PIC X variables to a COMP-3 variable, but in some special cases even that can work.

When does numeric data conversion occur in COBOL?

Numeric Data Conversion If you MOVE or perform a math calculation using any sending field type (group or element) to any receiving individual element field defined using a numeric PIC clause — then numeric data conversion will occur for the receiving field.
