Hi,

Please clarify me as to why the following thing happens while using SuperC-3.13.

File-A (New file)

Line1: 123
Line2: 123
Line3: 555
Line4: 666
Line5: 777

File-B (old file)

Line1: 123
Line2: 123
Line3: 888
Line4: 999
Line5: 000

My Expectation of SuperC output:

I 555
D 888
I 666
D 999
I 777
D 000


Observed Output:

I 555
I 666
I 777

D 888
D 999
D 000

Please note that i am using Delta option for display.

Hi,

You'll notice that the listing that you'd like to see is logically equiv to the actual listing.

The actual list states, in effect, that the 3 consecutive lines displayed from the old file beginning at line n and ending at line n+2 have been replaced by the 3 lines displayed from the new file.

Your list states that old line n displayed here was replaced by new line n;
old line n+1 displayed here was replaced by new line n+1 and finally;
old line n+2 displayed here was replaced by new line n+2.

I would guess that because they are contiguous non-matching recs SUPRCl groups them together... saving some print lines?

Does that cause a problem for you or are you just curious? If it causes a problem give soMe further detail. Maybe someone can come up w/a workaround.

Hi Jack,

Thanks a lot for ur reply.

Regarding the SuperC, the issue is that its behaviour doesn't seem to be consistent. I am trying to compare two large files (records running into lakhs) and i would like to see the results like the actual listing(list2) in the example discussed. But Super-C lists some differences like list1 (my expectation) and some like list2.

I am interested to know the difference so that i can try and get the listing like list1.
