4  PROBLEMS ADDRESSED IN VAXCXXL01_062 KIT


      o  When the Complex Library exp() function  detects  an  underflow
         error,  the  resulting  value  is  now  (0,0)  instead  of (+/-
         max-float, +/- max-float).

      o  The division routines within  the  Complex  Library  now  catch
         divide-by-zero errors instead of signalling them.

      o  The String extraction operator now takes  care  of  dynamically
         allocating the String to accommodate the input.

      o  When you open a file specifying ios::ate but  not  ios::app  to
         the  filebuf  open()function,  the  file is no longer opened in
         O_APPEND mode.  This incorrect behavior caused all data  to  be
         written  to the end of the file, regardless of the current file
         position.
