write a file by jumping lines, but without erasing them

[nicolas74]

Does someone know how to write a text file in lisp but --> by jumping some lines, but without deleting them? ?
I can write the file and if I do \n or \r actually skips the rows, but the ones that skips the deletes! ! !
I would like to keep the text already written in the file and write to a certain line (which is not the last)
Thank you

I don't think there's a pointer in the text line.
I think you should open a new file, read the original file and transcribe it line by line in the new file by inserting in the desired points the new content. Once finished delete the old file and rename the newly generated one.
