Comparing HEXADECIMAL values from two different files

Hi all,,

I have something odd to do..
I need to read hexadecimal value from two different files and compare those and carry out some operations.

When I use the below code,

Hi All,

To be more clear,

This is the value that is in the file - "Âº_ Â±Ã•Ã²"

And I tried displaying this in the COBOL as soon as I read the file and this was the value displayed - " Â³6; A "

I dono what is causing this mismatch. I have used PIC X(10) in my COBOL.

The code set used for the display that you view probably does not handle it the same as whatever utility you use to display the file. Always display the hex values. What you are seeing are the printable/displayable sets.

Hi Brenholtz ,

My code/logic does not require to display what is in the file. I just need to compare.

I have put that piece of information just for the understanding.
Appreciate if you can explain more.

Cheers,
Neo

3.4 browse the file and set hex on.....
In your program, define the value to compare to as hex instead of character.....

Hi William

Can you explain on more how to define the value to compare as a HEX character.

Sorry to keep you disturbing..

Thanks
Neo

for example, your "Âº_ Â±Ã•Ã²" showed up as:

Hi william,

Sorry that I mislead you.
I may not be knowing this value "Âº_ Â±Ã•Ã²" until I read the first file.
and the one more field to compare with will come from another file.

I need to compare these two unknown variables.

Thanks a lot for your help

As in?

Hello,

You need to look at both files in hex (as suggested above - do this in tso/ispf). When you have looked at the "same" data field a record in both files, post the hex values you see here and we can tell you more about your data. This investigation will not need your program to run.

When you post the values here, please use the "Code" tab at the top of the Reply Panel. Use copy/paste rather than typing the info. This will ensure your data is more readable. After you enter what you want to post, click Preview and ensure your post looks the way you want it to look.

Yes I have to compare exactly like this,

feellikeneo · New User Joined: 19 Mar 2007 Posts: 73 Location: Chennai

This is the data from my file-1,

How about showing us your data layout (working-storage) in your COBOL program. If indeed these are the same when you edit/view/browse them with HEX ON, then your address assignments for file1-field and file2-field are not what you think they are.

This is my IF condition,

William Thompson · Posted: Wed Aug 01, 2007 9:30 pm

The basic truth, if both values are coming from file, don't do anything, just move the one to your array and compare the other to it....Who cares that it doesn't display right.....

IIRC, when in spool, hex on doesn't work, but set hex on does.....

I am sorry that this doesn't work in my case.

I am just comparing these two values from file-1 and file-2 but still then my IF fails

William Thompson,
That is what he is doing. He is moving 8 bytes from someplace to some array position. and comparing one or another of the array positions to somplace in a FD record description

feellikeneo's addressing (relative locations) is wrong.

We need to see the complete records from the FD section and his move code to see where his addressing is incorrect............................

A side note; feellikeneo, not that it is completely necessary, but why are you working in the FD Record description entries and not from work-areas (i.e. why are you not using a workarea option with your reads)?

Have you tried defining the fields as COMP and comparing?

Hi Brenholtz ,

I tried moving both the values from file-1 to file-2 to working storage variable and then tried to compare. Still the same result.

Hi Socker_dad,
I tried COMP and sorry, no use

OK, here's the my resort. Post your code and the file. Like this:

Code:

ok.. let me try and get back to you

Hello,

I'd suggest making sure that RB-INDEX has the correct value and also making sure the table was actually loaded - if the values were moved to the array, but the position in the array was not incremented, the "load" would execute, but the array would not have all of the values.

I'm also confused why

Hello,

It should if it is copied from a browse with "hex on". . . .

That of course means the info needs to come from the actual data files rather than the sysout after it has been thru some amount of code.
