8 * Added dynamic memory allocation on encoding (whew). Code is now somewhat
9 * neater. We'll make the same change for decoding one day.
11 * Revision 1.9 1995/03/28 09:15:49 quinn
12 * Fixed bug in the printing mode

18 * Fixed serious stack-bug in odr_cons_begin
20 * Revision 1.6 1995/03/08 12:12:23 quinn
21 * Added better error checking.
23 * Revision 1.5 1995/02/10 18:57:25 quinn
24 * More in the way of error-checking.
