"There is no problem that cannot be solved by adding one level of
indirection."  Somebody like Dijkstra said something like that.

What you can do is have awk generate a shell script containing the cat
commands:

	awk ' S1 == "The proper line" {print "cat file1"}' | sh

Have fun.

awk '
	{
		if ($1 == "#include")
			system("cat " $2)
		else
			print
	}'

I don't have a SVR3 system handy just now, but I believe you will
find that this awk program copies its input to its output, replacing
lines of the form

	#include some_file

with the contents of some_file.
