Hi All
I have one query,say i have a requirement like the below code should be
move to diffent files whose maximum lines can be of 10 lines.Say in the below example,it consist of 14 lines.
This should be moved logically using the data in the fisrt coloumn to file1 and file 2.The data of first coloum should
not be present in both files(file 1 and file2 for a value i.e in the below example 102103 should be in on file only.In the below
example 102103 has 8 lines and i cannot place all in file 1 bcos it will exceed the maximum lines of file(10) .
