Awk script returns nothing
Code:
HSLIST=$1

LFILE=$2

STRING=$3

awk 'BEGIN {
  while((getline < "'${HSLIST}'")>0)
     S[$0]

  FS="\n"; RS="}\n"
}

/servicestatus {/ && /service_description='${STRING}'/ {

  for(X in D) delete D[X];

  for(N=2; N<=NF; N++)
  {
       split($N, A, "=");
       D[A[1]] = A[2]
       i = 3;
       while (i in A) 
          D[A[1]] = D[A[1]] "=" A[i++];
  }

  if (D[" host_name"] in S)
       printf("%s -------- %s -------- %s -------- %s -------- %s -------- %s -------- %s -------- %s\n", D["host_name"], D["service_description"], D["check_execution_time"], D["check_latency"], D["last_check"], D["last_hard_state_change"], D["current_state"], D["plugin_output"])

}' $LFILE

Can someone please explain to me why the above code isn't pulling out anything from a file that contain several chunks like the one below?

when i run the above code, i get back nothing.

synopsis:

i have a file that contains several of the chunks below. the chunks belong to several servers. one server may have several chunks associated with it.

in the below example, this specific chunk belongs to a server called "sky-01.net". there may be other chunks like this in a file, with service description "CPU_CHECK", "DISK_CHECK", etc.

urlcoding

URLCODING(3)						 libbash urlcoding Library Manual					      URLCODING(3)

NAME

     urlcoding -- a Libbash library for encoding and decoding URL's.

SYNOPSIS

     urlEncodeString [-l] <STRING>
     urlEncodeFile [-l] <FILE>
     urlEncodeStream [-l]
     urlDecodeString <STRING>
     urlDecodeFile <FILENAME>
     urlDecodeStream

DESCRIPTION

     urlcoding is a collection of functions that convert ASCII-text to standard URL's and vice-versa. The AWK code used is based on code by Heiner
     Steven <heiner.steven@odn.de>

     The function list:
	   urlEncodeString  Creates a URL from an ASCII string
	   urlEncodeFile    Converts a file into URL-valid text
	   urlEncodeStream  Converts standard input into URL-valid text
	   urlDecodeString  Converts a URL-encoded text back to a plain-text form
	   urlDecodeFile    Coverts URL-encoded text in a file back to plain text
	   urlDecodeStream  Converts URL-encoded standard input to text

     Detailed interface description follows.

     The [-l] option for the encoding functions should be used when line-feed characters ('
') are to be encoded as well.

     All functions print the results of their conversions to standard output.

     The exit status of all functions is that of the command 'awk', with '0' for success

FUNCTIONS DESCRIPTIONS

   urlEncodeString [-l] <STRING>
     Converts STRING - a string of ASCII characters - to URL.

   urlEncodeFile [-l] <FILE>
     Coverts FILE of URL-encoded text to plain text

   urlEncodeStream [-l]
     Converts text from standard input to URL-text.

   urlDecodeString <STRING>
     Converts URL-encoded string STRING back to text.

   urlDecodeFile <FILENAME>
     Converts the URL-encoded text in FILE to plain text.

   urlDecodeStream
     Converts the URL-encoded text from standard input to plain-text
