Code:
123
234

543


111
234


198

I would like this extract to be replaced by:
Code:
123
234
234
543
543
543
111
234
234
234
198
198

I wrote a simple script to do the job that reads myfile.txt and Would anybody have a suggestion?
Cheers, Bagvian

Hello bagvian,

Could you please let us know if this is a typo or it is real, your all Output sample looks fine apart from last digit 198 which comes into a space which is before it? All other digits are filling spaces which are coming after them, so could you please confirm on this?
Also if this is not a typo then kindly do let us know what all are conditions where you need this kind of output please.

Thanks,
R. Singh
