ccc_con,CCC_CON,0
The commas are not actually there when invoking the script, are they?

Either way, the code does something, in my opinion, very silly. For each line in this "arch_table_list.txt", it :
  • prints out the first column of arch_table_list.txt, followed by the first column of the file CCC_CON.
  • prints out the second column of arch_table_list.txt, followed by the second column of the file ccc_con
  • prints out the third column of arch_table_list.txt, followed by the third column of the file "0"
That seems a bit crazy.

basename

basename(1)							   User Commands						       basename(1)

NAME

       basename, dirname - deliver portions of path names

SYNOPSIS

       /usr/bin/basename string [suffix]

       /usr/xpg4/bin/basename string [suffix]

       dirname string

DESCRIPTION

       The  basename  utility deletes any prefix ending in / and the suffix (if present in string) from string, and prints the result on the stan-
       dard output. It is normally used inside substitution marks (``) within shell procedures.

   /usr/bin
       The suffix is a pattern defined on the expr(1) manual page.

   /usr/xpg4/bin
       The suffix is a string with no special significance attached to	any of the characters it contains.

       The dirname utility delivers all but the last level of the path name in string.

EXAMPLES

       Example 1: Setting environment variables

       The following example, invoked with the argument /home/sms/personal/mail sets the environment variable NAME to the file named mail and  the
       environment variable MYMAILPATH to the string  /home/sms/personal:

       example% NAME=`basename $HOME/personal/mail`
       example% MYMAILPATH=`dirname $HOME/personal/mail`

       Example 2: Compiling a file and moving the output

       This  shell  procedure,	invoked  with  the argument /usr/src/bin/cat.c, compiles the named file and moves the output to cat in the current
       directory:

       example% cc $1
       example% mv a.out `basename $1 .c`

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect  the execution of basename and  dirname:  LANG,  LC_ALL,
       LC_CTYPE, LC_MESSAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.
