Re^2: I still can't get only the necessary lines from the file.

Oops -my mistake.I have the correct line in my code's unless. \* Exit context \*
The problem is that in print results I get lines that are not between the closest "Start context" and "* end context *".
I suspect that maybe the problem is in this line:
if (/Start context/ .. /\* End Context \*/)
which IMHO takes all the lines between the first "Start context" in the file and last "* end context *"
. Am I right? Or the line:
if (/Start context/ .. /\* End Context \*/)
looks for the closest "Start context" and "* End context *"
Thanks

The `..` "flip-flop" operator (see perlop) is true "between" the two operands. That is, once the left-hand match is true, the flip-flop is true, until whenever the right-hand match succeeds. Then it's false until the left-hand match is true, and so on. So, no: `if (/Start context/ .. /\* End Context \/) {` doesn't "take" "all the lines between the first 'Start context' in the file and last ' end context *'", but indeed only those within any of the contexts (and the start marker too, but not the end marker).
