Question

Thanks for your reply ...... shell_life .....

It is working fine , but I am getting P3 records above P1

For eg the input file is:

If I am searching the number 9881119347
Code:
P1
123
P2
9881119347,87
P3
9881119347
P1
998811347
P2
34534
P3
98811147
P1
78686
P2
902384930284
P3
2904898


Then the output generating is:
Code:
9881119347
P1
998811347
P2
34534
P3
98811147
P1
78686
P2
902384930284
P3
2904898


But it should be like below:
Code:
P1
998811347
P2
34534
P3
98811147
P1
78686
P2
902384930284
P3
2904898

I am searching only till P3..but I have to search before the next P1 occurs...Please check the output that is required.


Kindly advice
