HEIDENHAIN ITNC 530 - PILOT SMART NC Manual page 150

Using machining positions repeatedly
You can use machining positions for all programmed machining units that
directly follow, regardless of whether you have created these machining
positions directly on the form or as an HP file in the pattern generator.
Just leave the input fields for the machining positions empty. smarT.NC
then automatically uses the machining positions previously defined by
you.
Machining positions stay effective until you define new
machining positions in any subsequent unit.
