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.

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 comp3 to comp3?

Re: Move comp-3 to comp-3. If the sending field has more digits to the left (or right) of the decimal point than the receiving field, truncation will occur. If the sending field has fewer digits to the left (or right) of the decimal point, zero will be used to fill the extra positions.

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 the difference between comp and COMP3 in COBOL?

It is the default internal representation of the data. Any type of data can be specified with the DISPLAY internal representation….Difference between COMP and COMP3.

COMP	COMP3
COMP does not occupy extra space to store sign.	In COMP3 sign in compulsorily stored at right side and thus it occupies an extra space.

Can we move alphanumeric to comp-3?

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 COBOL display Comp variable 3?

Can we move alphanumeric to comp3 in COBOL?

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 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).

Which is better comp or COMP3?

We can use only 9 and S in PIC Clause. We can use 9 , S , V in PIC Clause. 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.

Can we move alphanumeric to COMP3 in Cobol?

Is COMP or COMP-3 better?

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 redefine COMP three variables?

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 read Comp-3?

How to convert Comp to numeric in COBOL?

You don’t “convert COMP to numeric”, because COMP is a subset of numeric. SUBTRACT, COMPUTE, etc. A COMP item (or COMP-3, etc.) is a numeric item platform and compiler. Numeric fields which are *not* defined as one of be printed or displayed, because each digit is stored as a byte. For all way, and COBOL will do the necessary conversion.

How many lines of COBOL does it take to run a mainframe?

The current generation of mainframes performs tens of millions to hundreds of millions of lines of COBOL code for every second of CPU time. Unless you have something being done, literally, BILLIONS or TRILLIONS of times, then you are not likely to ever be able to see performance differences.

How to compare alphanumeric and numeric data?

What type of comparision are you looking for. Do you really want to compare character values. Your alphanumeric variables have numeric data in them. If thats the case, then better you redifine both your alphanumeric variables as numeric ones and then do comparision with their numeric counter parts.

Is comp-3 (packed-decimal) field a good key?

Usually, comp-3 (packed-decimal) fields do not make good keys due to the signs. This does not clarify it. You need to show that key data in both of the files. Please use code tag since actual positions are important. 9 (12) and 9 (14) elementary levels is fine.
