Hi,

I need to tabulate a certain expression dependent on variable x,
for a number of x values, using arbitrary precision (the expression is
badly conditioned). I need at least 20 correct significant digits.
I had an example showing how to do this, but 
unfortunately I have not saved that file, and now I have to do this again,
but I am not very familiar with MATHEMATICA. Perhaps someone will
agree to refresh my memory and give a proper example.
