Some anomalies have been assailing me or my newly accquired used HP-28S.
None of the phenomena have been reproduced, so I am not certain of the 
nature of their existence.  A few weeks ago, I was able to create a 
global variable whose name does not appear in the user menu.  I remember 
that the name I used consists of a degree symbol.  However, when I tried 
it again  later, the variable's name was on the "user" menu.  Yesterday, 
after idling for a few minutes, the calc. insists on inserting a "B" whenever 
I pressed one of the four arrow keys.  This happened when the calc. was in 
either "Edit" mode or was with some standard_menu.  But it was definitely 
not the letter "B" that the key I was pressing corresponds to.  I have 
been so far unable to reproduce this.  Today, I turned off my calc. while 
it is in edit mode.  After I turned it on again, the cursor freezed, that is 
to say that it is not flashing or responding to arrow keys.  After I pressed 
ATTN (ON), it went back to normal.  When I entered EDIT mode again, the 
cursor moved on my command as it was supposed to.  I am very puzzled by 
these stange phenomena.  I would appreciate if anyone could enlighten me on 
these matter.  Incidentally, I have suspected that low batter might be the 
culprit because my HP-28S' batteries have never been changed; however, the 
low battery annunciator is not on yet.

Incidentally, could anyone post and tell me where to find a bug list for 
HP-28S.

Thanks
