SUBROUTINE GENNBO
************************************************************************
For Mac OS X users, a "SAVE CORE" command should be inserted after
first declaration of the CORE(MEMORY) array near the beginning of 
SUBROUTINE GENNBO, as shown below:

      PARAMETER(MEMORY = 10000000)
      DIMENSION CORE(MEMORY),NBOOPT(10)
      SAVE CORE

This prevents the large array CORE from being put on the stack,
which is not sufficiently large (nor adjustable in size) to handle
this array in the Mac OS X system.
