Try this awk program:
Code:
#!/usr/bin/awk -f
#Awk program : paste.awk

function readFile(i,    rec) {
   if (getline rec < ARGV[i])
      return rec;
   else {
      ++eof[i];
      return "";
   }
}

BEGIN {
   while (1) {
      rec1 = readFile(1);
      rec2 = readFile(2);
      if (eof[1] && eof[2]) break;
      printf("%-60s%s\n", rec1, rec2);
   }
   exit;
}

Output:
Code:
$ awk -f paste.awk file1.txt file2.txt
apples                                                      red
grapes                                                      green
oranges                                                     orange
lemons                                                      yellow

igawk

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
