Is that the way your conf file has to be, or can you reorganize it as you please? That's not how I'd have organized it, it takes a bit more processing that way... Just simple files like
Code:
name1 surname1
name2 surname2
name3 surname3

would be much simpler for awk to handle.

But as is, if you slap a BEGIN { ... } around the data you have, awk can actually run it. Then you just need a few loops to split and reorganize it into something you can easily look up.

Code:
$ cat awkarr.sh

#!/bin/sh

# Create a file full of awk code to run
cat <<EOF > /tmp/$$
BEGIN {
        # Slurp the contents of your config file into this bit of awk
        `cat conffile`

        # Get arrays into form A["name"]=1 for easy lookup later
        for(X in tab1)
        {
                split(tab1[X], A);
                for(X in A)     T1[A[X]]++;
        }

        # Add a " since the extra quotes on the first and last record
        # aren't all eaten by FS
        for(X in tab2)  T2[tab2[X]"\""]++

        FS="\",\""
}

# Dollar only needs escaping because its in a here-document
T1[\$2] && T1[\$3] && T2[\$12]

EOF

awk -f /tmp/$$ data

rm -f /tmp/$$

$ ./awkarr.sh

"aaaaa","surname1","name1","ddddd,eeeee","ffffff","ggggg","3","2012/02/22 12:25:21","2012/02/22 00:00:00","8","hhhh","First"

paps

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.
	      Please notice this option isn't related to the terminal length as in a "80 culums terminal".

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do right to left (RTL) layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.

       Postscript points
	      Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.

       --bottom-margin=bm
	      Set bottom margin. Default is 36 postscript points.

       --top-margin=tm
	      Set top margin. Default is 36 postscript points.

       --left-margin=lm
	      Set left margin. Default is 36 postscript points.

       --right-margin=rm
	      Set right margin. Default is 36 postscript points.

       --gutter-width=gw
	      Set gutter width. Default is 40 postscript points.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
