RE: Comparing two records of a file

The internally described method will still work & it does not mater whether
the data is character or numeric.  It is just a string of data.  Printing it
out means that you would have to define the printed fields.

For one file you can...

Read file1
Temp1 = Data1
Read file1
If Data1 <> Temp1
Etc.

Or you can create a logical over the file & have it as file2.

Thanks for the reply guys.

But I think there is some misunderstanding.  Actually
there is only one file and in that file two records
needs to be compared.  Please note that the fields of
the file are numeric in between.  I don't really want
to compare field by field and I am looking for
something better.

Please let me know if there is still any confusion.

Thanks,

Gopal
