How do I cut out a piece of text?

[Emile van Sebille]

After reading the file contents into a variable, split
it into fragments using string.split(txt,"\n  DEF").
Then pick the piece you want to copy, replace the "DEF"
and write it to the file.

HTH,


PS This works well if the text you're working with is
as highly consistent as your example.
