That is several useless uses of awk and backticks... You could just do

Code:
for FILE in file1 file2 file3 file4 file5 file6 file7 file8
do
...
done

or

Code:
while read FILE
do
...
done < list.txt

Also, why should it be printing what you want? You're telling it to print x lines, you get x lines.

Also, why should it be printing the new values? You stored the old values in the array, and that's what you get.

You don't need to do either of them. You don't need an array, and you don't need to store all the old values.

In fact you don't need a loop at all, awk is quite capable of handling more than one file all by itself.

So:

Code:
# Store these things in a file for awk to grab easily
cat >trans.txt <<EOF
AAA,-10
BBB,20
CCC,30
EOF

awk -F"," -v OFS="," '

# Load data from trans.txt, the very first file
NR==FNR { T[$1]=$2; next }
# Translate data if found in array
$8 in T { $8=T[$8] }
{ print > FILENAME ".aaa" }' trans.txt file*

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.
