Adaptation of post #7 for the new requirements:

Code:
awk -v c=4 '
  !($1 in M) {
    M[$1]=$c
  }
  {
    if($c>-99.99 && $c<=M[$1]) {
      M[$1]=$c
      V[$1]=$2
    }
  }
  END {
    for(i in M) print i, M[i], V[i]
  }
' file

c is the column number

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
