Extract a block of text??
Hello all,

I have a large output file from which I would like to extract a single block of text.

An example block of text is shown below:

Code:
      ***** EQUILIBRIUM GEOMETRY LOCATED *****

   ATOM   CHARGE       X              Y              Z

What I need is the text under the line
Code:
      ***** EQUILIBRIUM GEOMETRY LOCATED *****

until the next blank line i.e, the line right after
Code:
 FLUORINE    9.0   7.3114031179   8.9380862348  13.6046918391

. Also, each of the columns of text should be separated by spaces or tabs i.e. the first column should be the atom name "MOLYBEDUM" the second column should be the atomic number "42.0" etc...


Thanks in advance
