Can numeric be converted to comp-3?
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 move packed decimal to numeric in Cobol?
This document describes how packed decimal values (Computational-3) can be converted to numeric values via File Master using COBOL copybooks. The only method to get this done is to use a File Master Reformat data set, aka. REFFILE. (“11 REFORMAT Convert file from one record layout to another”).
What is the difference between Comp and Comp-3?
Comp is a binary usage, while comp-3 indicates packed decimal. The other common usages are binary and display. IBM Mainframes are typically binary and AS400’s are packed. ‘
How is Comp-3 stored?
COMP-3 is the equivalent of PACKED-DECIMAL. 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.
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.
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 Z in COBOL?
As shown in the chart, the Z suppresses leading zeros by turning them to a space. 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.
Why do we use comp-3?
COMP-3 enables the computer to store two digits in each storage position, except for the rightmost position, which holds the sign. Suppose if you move 1234567 into a field defined 9(7). In DISPLAY mode, which is default, this field will use 7 storage positions.
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).
How many bytes Comp-3 will take?
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. (See COBOL Computational Fields for information on the comp data type).
How to move comp-3 field to numeric?
Please have a look into the manuals to understand how the COMP-3 fields will be displayed… First, t here is a link to manuals at the top of the page. Click on it, find the COBOL Language Reference and Programming Guide manuals. Learn to use them, for you will need them often.
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.
How to convert numeric to comp-3 ( packed decimal )?
I have a numeric value of 2011005. I want to convert the numeric value to COMP-3 ( Packed decimal). I have tried all methods for the past 2 weeks.. but i am not able to send the value in correct format.. I tried EBCDIC format also can anyone please help me in solving this.
Is the comp-3 field in Pic S9 ( 03 ) 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.
