As mentionned in a few messages recently it is not uncommon to make a
mistake and then get a huge output to be generated. When that happens,
one is either stuck for a long time or crashes.

A while back, support at Wolfram gave me this trick that I now have at
the top of any notebook manipulating large amount of data:

reallyBig[x_] := If[ByteCount[x] > 200000, "Too Large", x]; 
  $Post = reallyBig;

It will replace any "large" output by the string "Too Large". I cannot
count how many times this saved me. Hope it helps you too.

Experience as shown that 200000 enabled me to always see what I want.

Sincerely,
