Yes, you're right. Mac OS X uses <newline>; earlier versions of Mac OS used <carriage-return>. I use Mac OS X, but never did much with earlier versions of Mac OS and I had (incorrectly) assumed that earlier Mac OS operating systems used <carriage-return><newline> character pairs like DOS and Windows.
Note that if you're reading a Mac OS 9 or earlier format file and want the output in the same format, you need to set
ORS as well as
RS to <carriage-return> (i.e.,
ORS='\r'), and you need to change any
\n sequences in
printf format strings and in
print arguments to
\r.

IGAWK(1) Utility Commands IGAWK(1)
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
