The following seems to do what you want:
Code:
awk -v nof=123 -v OFS=, '
{	printf("%s%s", $1, OFS)
	f = 1
	for(i = 2; i <= NF; i++) {
		while(f < $i + 0 && f <= nof)
			printf("0%s", f++ < nof ? OFS : ORS)
		if(f == $i + 0 && f <= nof)
			printf("1%s", f++ < nof ? OFS : ORS)
	}
	while(f++ <= nof)
		printf("0%s", f <= nof ? OFS : ORS)
}' file

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 SEE ALSO
