I don't have a set of files of the size you want to use, but the following works for the samples you provided:

Code:

awk '
FNR == NR {
        h[$1] = NR      # set "h"igh end of input lines for this label
        m[NR] = $2      # save "m"inimum range value for this line
        M[NR] = $3      # save "M"aximum range value for this line
        l[NR] = $4      # save "l"abel from this line
        next
}
{       e = h[$1]       # set high line number for field 1 value on this line
        o = $NF         # set initial output line to label on this line
        oc = 0          # set number of matched lines
        # Loop through the ranges associated with field 1 from this input line
        for(i = h[$1 - 1] + 1; i <= e; i++) {
                if($2 < m[i]) continue  # range is too low; keep looking
                if(m[i] > $2) break     # range is too high; we are done
                if($2 <= M[i]) {        # we have a matching range
                        o = o " " l[i]  # add corresponding label to output line
                        oc++            # increment match count
                }
        }
        print o, oc     # print the matched labels and the match count
}' "file 2" "file 1"

As always, if you are using a Solaris/SunOS system, use /usr/xpg4/bin/awk or nawk instead of awk.
With your sample input, this script produces:

Code:

LABEL_A LABEL_7 LABEL_8 2
LABEL_B LABEL_9 1
LABEL_C LABEL_4 1
LABEL_D LABEL_1 1

which matches the Full output you said you wanted except your output showed a space instead of the underline marked in red in the last output line.

msql_fetch_row - Get row as enumerated array

SYNOPSIS

       array msql_fetch_row (resource  $result)

DESCRIPTION

       msql_fetch_row(3)  fetches one row of data from the result associated with the specified query identifier. The row is returned as an array.
       Each result column is stored in an array offset, starting at offset 0.

	Subsequent call to msql_fetch_row(3) would return the next row in the result set, or FALSE if there are no more rows.

PARAMETERS

	      o $
		result -The result resource that is being evaluated. This result comes from a call to msql_query(3).

RETURN VALUES

	Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.

EXAMPLES

       Example #1

	      msql_fetch_row(3) example

	      <?php
	      $con = msql_connect();
	      if (!$con) {
		  die('Server connection problem: ' . msql_error());
	      }

	      if (!msql_select_db('test', $con)) {
		  die('Database connection problem: ' . msql_error());
	      }

	      $result = msql_query('SELECT id, name FROM people', $con);
