```Hi

Has anyone come across a way of, say, setting a maximum amount of
output per cell?  I have several lists of 15,000 data points I need to
manipulate.  If I forget a semicolon, or have a typo, I am often
treated to a   five minute wait while Mathematica prints (an obvious
error message and) 15,000   irrelevant data points.

One can, of course, turn off some error messages with the Off[]
function, but this does not completely solve the problem.  What I want
is for   Mathematica to recognize I couldn't possibly want to see all
that stuff.

For a toy version of the problem, see below, and imagine many more
points:

In[8]:=
Off[General::spell1]

In[9]:=
sins = Table[N[Sin[2 Pi i/10]],{i,20}];

In[10]:=
ListPlo[sins]

Out[10]=
ListPlo[{0.587785,0.951057,0.951057,0.587785,

0,-0.587785,-0.951057,-0.951057,-0.587785,0,0.587785,0.951057,0.951057,
0.587785,0,-0.587785,-0.951057,-0.951057,-0.587785,0}]

Regards,

Brian
