BEGIN and END are part of an awk script: called within the fileformatting ksh function:
as they contain no statements they could be removed e.g:
In an awk script the BEGIN section runs once before any input is processed (e.g. to print file headers).
The END section is run once after all the input files have been processed (e.g. printing totals).

Why would you need to use this in a script?
Why can't you just use print to print out what you want printed in the begining and print for what you want at the end.
So this:
nawk 'BEGIN {print "this is the first line"}
{print $1 $2 $3}
{print $5 $6}
END {print "this is the last line"}'

Perl::Critic::Policy::ControlStructures::ProhibitLabelsWUserpContriPerl::Critic::Policy::ControlStructures::ProhibitLabelsWithSpecialBlockNames(3)NAME
Perl::Critic::Policy::ControlStructures::ProhibitLabelsWithSpecialBlockNames - Don't use labels that are the same as the special block
names.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
When using one of the special Perl blocks "BEGIN", "END", "CHECK", "INIT", and "UNITCHECK", it is easy to mistakenly add a colon to the end
of the block name. E.g.:
# a BEGIN block that gets executed at compile time.
BEGIN { <...code...> }
# an ordinary labeled block that gets executed at run time.
BEGIN: { <...code...> }
The labels "BEGIN:", "END:", etc. are probably errors. This policy prohibits the special Perl block names from being used as labels.
CONFIGURATION
This Policy is not configurable except for the standard options.
