This is probably a better question for comp.lang.c, so I've redirected 
the followups there.

Basically, you have three options:

1.  Declare the strings statically (outside of any funtions, or by using 
	 the 'static' keyword):

	 char string[10][1000];
    void main() {...};

2.  Declare the strings within a function ('auto'):

	 void main()
	 {
		 char string[10][1000];
       ...
    }


	 Note: on the Amiga you will need to set a large stack size in order
	 for this to run (say STACK 30000).  Otherwise you WILL crash the 
	 system.

3.  Declare the strings dynamically:

	 void main()
	 {
		 int i;
		 char *string[10];
		 for (i = 0; i < 10; i++)
			string[i] = malloc(1000);
			/* or, for the Amiga:  string[i] = AllocMem(1000,0); */
       ...
    }
