Nothing here is ksh-specific, so I changed it to use /bin/sh

Code:
#!/bin/sh
name=$1
print "$name"
nawk -v name="$1" '$1 == toupper(name){print""$1" is husband of "$2" & father of "$3""}'
exit 0

I think you are expecting the redirections (>$out etc) to assign the output to a variable, but it doesn't do that. It sends the output to a file whose name is $out

Like Annihilannic tried to explain, the syntax for assigning the output from a command to a variable is var=`commands` or equivalently var=$(commands) ... but unless you need the variable for something else than just printing it immediately, using variables at all is unnecessary.

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
