IG_ISIS_drv_start_zone is one of several hierarchical data transfer functions that are called automatically by the IG_ISIS_drv_run_zone function. The hierarchy of data transfer functions is:

 
Copy Code
IG_ISIS_drv_start_stack
     IG_ISIS_drv_start_page
          IG_ISIS_drv_start_zone
               IG_ISIS_drv_forward
                    IG_ISIS_drv_start_data
                         IG_ISIS_drv_put_data
          IG_ISIS_drv_end_zone
     IG_ISIS_drv_end_page
IG_ISIS_drv_end_stack

Most scanners do not support the concept of multiple zones, and will therefore ignore this message.
