Hello Everyone...
Thanks for your responses!!!
I need to divide my huge data file into smaller files (of say 10 MB or so). I have to feed this file ( as smaller sub-files) into another program.
The line numbers in each file vary. The program cannot take a huge file together, and needs chunks of data!!
I hope I am a little more clear now??
Thanks!
