   why not detect that in your script with diff or compare?   
      
   simplistic eg:   
   @echo off   
   set newhatch=no   
   rem set a non-changing name to hold our current netseg   
   rem myseg.cur is the current netseg that is published   
   iff not exist myseg.cur copy myseg.now myseg.cur   
   makenl                       ; output is myseg.now   
   diff myseg.cur myseg.now   
   if errorlevel 1 set newhatch=yes   
   if '%newhatch%' == 'no' goto end   
   rem diff says there's a difference between the files   
   rem so let's update the current one with the new one   
   copy myseg.now myseg.cur   
   rem and hatch it   
   hatch area whatever file myseg.cur desc "my new netseg" replace myseg.cur   
   rem all done!   
   :end
