Problem between Octave2.1.50 and OCST / hold does not work?

[ผศ.ดร.ศุภชัย วรพจน์พิศุทธิ์]

>From my last post, I would like to confirm that there may have some
conflict between Octave2.1.50 and OCST. The following code does not work
for version 2.1.50a (precompiled Windows and precompiled Mandrake) but
works on version 2.1.42 (precompiled Windows).

>> motor = tf2sys([4500],[1 361.2 0]);
>> PI = tf2sys([1 0.1],[1 0]);         % This is PI so it is proper TF (1
pole/1 zero)
>> G = sysmult(motor,PI);
>> bode(G)

Anyway, I can not use hold command for both 2.1.50 and 2.1.42. This
command is not implemented yet?
