If you can be much clearer about what it is that you want, you may get an answer.
A little bit of thought might suggest if not possible/copmplicated with three it would be possible with two.
Take two files and join them together, not excluding/splitting anything. Then take the new file and the third file and do what you actually want to do. So you probably have a "fall-back".
Now, the usual, details of inputputs/outputs. Samples of inputs/outputs. Results of what you have tried so far/don't understand. How it failed. Etc. |

Give some more details about your requirement.
What are the details available in your files.
What do you want to compare?
Can I compare 3 files: Yes
How? : depends on your requirement. |

<dumb> business requirement as posed ...
the output is going to be pretty unmanageable
think about the number of outputs requrred
1 ) record in A not in B not in C
2 ) record in A not in B ... in C
3 ) record in A .. in B not in C
repeat for B and C and eliminate the duplicates
and meditate about the complexity and the futility of the issue
anyway unless I am blatantly wrong here are the otuputs needed
| Code: |
record ... in A ... in B ... in C
record ... in A ... in B not in C
record ... in A not in B ... in C
record ... in A not in B not in C
record not in A ... in B ... in C
record not in A ... in B not in C
record not in A not in B ... in C

the only case where a 3 diffs is needed is in a clumsy/dumb programming environments
where two independent program changes are to be merged to produce a congruent final program |

i had 3 files, and having matching/mismatch account numbers.
So i used the ICETOOL SPLICE by matching first and second files in one step, and 2nd & 3rd file in other step, then i compared these two subsets with another splice to produce the common entries. |

Hello,
Good to hear it is working - thank you for letting us know 
Your solution is a good way unless you want to design and implement a 3-file match merge. Not as simple as a 2-file match/merge, but has been done many tmes 
Depending on the release level of the sort product, you might also look at JOINing the files rather than SPLICEing. |
