There seem to be multiple issues with this code:
  • there is semicolon missing between the first two gsubs, is that a typo?
  • also the third gsub seems to have a spurious v=$2 in it, and if you leave that out it becomes identical to the the first gsub, so the third serves no purpose
  • There is a single quote missing at the end of the awk statements
  • In the field separators specification -F '[= '':;.]' the two quotes in the middle serve no purpose. Also also it seems ill adapted to splitting fields of the input file. With the given input $1 will only ever contain "MEMSIZE" and so that is the only time that the $1 in L condition is true, but then $2 is empty, but since the label in array L is "MEMORIZE " with a trailing space, even that will not match.
  • K[2]>'5:00:00' contains single quotes instead of double quotes, so this evaluates to K[2]>5:00:00, which is a syntax error

perl::critic::policy::valuesandexpressions::prohibitquotesasquot

Perl::Critic::Policy::ValuesAndExpressions::ProhibitQuPerl::Critic::Policy::ValuesAndExpressions::ProhibitQuotesAsQuotelikeOperatorDelimiters(3pm)

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitQuotesAsQuotelikeOperatorDelimiters - Don't use quotes ("'", """, "`") as delimiters
       for the quote-like operators.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       With the obvious exception of using single-quotes to prevent interpolation, using quotes with the quote-like operators kind of defeats the
       purpose of them and produces obfuscated code, causing problems for future maintainers and their editors/IDEs.

	   $x = q"q";		     #not ok
	   $x = q'q';		     #not ok
	   $x = q`q`;		     #not ok

	   $x = qq"q";		     #not ok
	   $x = qr"r";		     #not ok
	   $x = qw"w";		     #not ok

	   $x = qx`date`;	     #not ok

	   $x =~ m"m";		     #not ok
	   $x =~ s"s"x";	     #not ok
	   $x =~ tr"t"r";	     #not ok
	   $x =~ y"x"y";	     #not ok

	   $x =~ m'$x'; 	     #ok
	   $x =~ s'$x'y';	     #ok
	   $x = qr'$x'm;	     #ok
	   $x = qx'finger foo@bar';  #ok

CONFIGURATION

       This policy has three options: "single_quote_allowed_operators", "double_quote_allowed_operators", and "back_quote_allowed_operators",
       which control which operators are allowed to use each of "'", """, "`" as delimiters, respectively.

       The values allowed for these options are a whitespace delimited selection of the "m", "q", "qq", "qr", "qw", "qx", "s", "tr", and "y"
       operators.

       By default, double quotes and back quotes (backticks) are not allowed as delimiters for any operators and single quotes are allowed as
       delimiters for the "m", "qr", "qx", and "s" operators.  These defaults are equivalent to having the following in your .perlcriticrc:

	   [ValuesAndExpressions::ProhibitQuotesAsQuotelikeOperatorDelimiters]
	   single_quote_allowed_operators = m s qr qx
	   double_quote_allowed_operators =
	   back_quote_allowed_operators =
