Description:
   This  program  will  calculate  first  derivation of a given function.
   (SOL program uses this small routine).

Usage:
   Store  in  variable  X  x-coordinate  of  a  point  you  want  to know
   derivation  value.   That's  all.   There is no 'input' section, since
   main  usage  for  this program is to pass derivation value back to the
   Equation  solver  program.   <FUNC>  is  the  program which holds your
   equation.
