hello

I have a file that looks like the example below - and i need a snippet of code that condenses the file as shown in the example - i can read the file line by line - but can anyone tell me how to compare with the rest of the file? 

A:1  B:2  C:3 D:4  CNT:1 STR:1 END:2
A:1  B:7  C:3 D:4  CNT:1 STR:2 END:3
A:1  B:2  C:3 D:4  CNT:1 STR:3 END:4
A:2  B:2  C:3 D:5  CNT:1 STR:4 END:5
A:2  B:2  C:3 D:5  CNT:5 STR:5 END:10
A:3  B:2  C:3 D:4  CNT:1 STR:11 END:12

should become 
A:1  B:MULTIPLE  C:3 D:4  CNT:3 STR:1 END:4
A:2  B:2  C:3 D:5  CNT:6 STR:4 END:10
A:3  B:2  C:3 D:4  CNT:1 STR:11 END:12

Any help would be appreciated.
