  Well, while Ptr's have been known to nibble on me, they rarely bite (but when
they do!!!).  Any pointer will do (Ptr = pointer).  Some examples:

	int ptr1[10], *ptr2;  long len;  Str255 str;
	/* some code */
	len = sizeof(int) * 10;  FSWrite (refNum, &len, ptr1);

	/* or */
	ptr2 = ptr1;
	len = sizeof(int) * 10;  FSWrite (refNum, &len, ptr2);

	/* or in your case */
	strcpy (str, "a line of text\ranother line of text");
	len = strlen(str);
	FSWrite (refNum, &len, str+1);

  Please, cash only, and in small denominations.
