	It's easier than that.  Just do the following to your code:

Change:
>test.c:

To:
>test.c:

>	{

	This trick only works with Manx.  Some further comments:

--------
		Delay(100L);
		kprintf("Testing\n");
	}
ldr.c:
	#include <exec/types.h>
	main()
	{
		ULONG seg,LoadSeg();

		seg = LoadSeg("test");
		if (seg == 0)
		{
			printf ("Can't Load 'seg'\n");
			exit(1);
		}

		if (CreateProc("TEST",0L,seg,500L) == 0)
		{
			printf ("Can't CreateProc()\n");
			exit(1);
		}
		printf("done\n");
		/*
		 * No, you're not.  You should hang around and wait for
		 * your created process to finish executing, and then
		 * UnloadSeg() it.  Otherwise, you'll have a memory leak.
		 */
