/*
 *	Function	BuildIntuiText
 *	Programmer	N.d'Alterio
 *	Date		22/09/95
 *
 *  Synopsis:	This function builds a linked list of IntuiText structures
 *		containing the FullInfo structures information ready for 
 *		printing. The linked list is of fixed length so that the
 *		news list blanks the contents of the mail list when they 
 *		switch and vice versa.
 *		To free the linked list call FreeIntuiText.
 *
 *  Arguments:	struct IntuiText *base_it		IntuiText structure used for
 *							intialisation.
 *		struct FullInfo *fi			FullInfo structure containing 
 *							information to print.
 *		int max_lines				Length of linked list.
 *
 *  Returns:	struct IntuiText *			Filled in IntuiText structure.
 *		NULL					If error.
 *
 *  Variables:	 i					Loop variable.
 * 		 error					Error flag;
 *		*it					Start of linked list. Returned 
 *		*cur_it					Temp IntuiText pointer.
 *		*cur_fi					Temp FullInfo pointer.
 *
 *  Functions:  AllocIntuiText				Allocates IntuiText struct (SW)
 *		FreeIntuiText				Frees IntuiText struct/linked 
 *							list (SW)
 *		sprintf					Prints to a string (EXEC)
