Hi.

The solution posted by fpmurphy worked in the Linux I use:
Code:
#!/bin/bash -

# @(#) s1       Demonstrate feature.

echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version =o $(_eat $0 $1) awk

FILE=thousands.awk
cat >$FILE <<'EOF'
BEGIN { printf "%'d\n", 1234567 }
EOF

echo
echo " awk script:"
cat $FILE

echo
echo " Results with LC_ALL=C:"
LC_ALL=C gawk -f $FILE

echo
echo " Results with LC_ALL=en_US.UTF-8:"
LC_ALL=en_US.UTF-8 gawk -f $FILE

exit 0

Producing:
Code:
% ./s1
(Versions displayed with local utility "version")
Linux 2.6.11-x1
GNU bash 2.05b.0
GNU Awk 3.1.4

 awk script:
BEGIN { printf "%'d\n", 1234567 }

 Results with LC_ALL=C:
1234567

 Results with LC_ALL=en_US.UTF-8:
1,234,567

Best wishes ... cheers, drl

printf

PRINTF(1)                                                          User Commands                                                         PRINTF(1)

NAME

       printf - format and print data

SYNOPSIS

       printf FORMAT [ARGUMENT]...
       printf OPTION

DESCRIPTION

       Print ARGUMENT(s) according to FORMAT, or execute according to OPTION:

       --help display this help and exit

       --version
              output version information and exit

       FORMAT controls the output as in C printf.  Interpreted sequences are:

       "     double quote

       \     backslash

       a     alert (BEL)

            backspace

       c     produce no further output

       e     escape

       f     form feed

       
     new line

       
     carriage return

       	     horizontal tab

       v     vertical tab

       NNN   byte with octal value NNN (1 to 3 digits)

       xHH   byte with hexadecimal value HH (1 to 2 digits)

       uHHHH Unicode (ISO/IEC 10646) character with hex value HHHH (4 digits)

       UHHHHHHHH
              Unicode character with hex value HHHHHHHH (8 digits)

       %%     a single %

       %b     ARGUMENT as a string with '' escapes interpreted, except that octal escapes are of the form  or NNN

       %q     ARGUMENT  is  printed  in  a format that can be reused as shell input, escaping non-printable characters with the proposed POSIX $''
              syntax.

       and all C format specifications ending with one of diouxXfeEgGcs, with ARGUMENTs converted to proper type first.  Variable widths are  han-
       dled.

       NOTE:  your  shell  may  have its own version of printf, which usually supersedes the version described here.  Please refer to your shell's
       documentation for details about the options it supports.
