Thanks Nikola and Bob.
Would "anchoring with \z" tantamount to having a
trailing "$"? In other words, are the following
expressions one and the same?
/^[0-9a-fA-F]+\z/
/^[0-9a-fA-F]+$/

in scalar context, it returns false until left is true. then returns true

what exactly does '/START_KEYWORD/.../END_KEYWORD/' mean?
I see a regex -> /START_KEYWORD/
an ellipsis -> ...
and a regex -> /END_KEYWORD/
you are saying the whole thing means something, but I don't understand
what.
you say 'the elipsis returns false'
what does that mean? w

i don't understand your answer. how will that match anything?
the first line matches the whole block ok, but then the match is dropped
by the '!' phrases
since they are in the text.
also, where is documented the ellipsis in a grep?
also, using two regexes on either side of the ellipsis?

I'm parsing a file with multiple Fortran-like blocks that look like:

I want only the contents of each block, not the keywords.

Hello all.
I've learned a bit about regular expressions today. I have a string formatted

following code which does work:

$username =~ s/(CN=)//;
