Hi All, I have a situation where i have to read a file for a particular value,convert the value into capital letters and then again rewrite into file. Now,i first opened a file in read mode and split a line and then converted into upper case using uc.But i want to only replace that particular field and not the whole file.Also i don't want to create a new file too. Can anyone of you guide me?
