endsuite

This terminates a suite definition. endsuite is also an implicit endfamily/endtask for all families/tasks currently being defined.

suite obs
   task t1
endsuite

endfamily

This terminates a family definition. AnchorendfamilyYou must use endfamily to terminate the current family in order to start a new family definition at the same level.
Typically endfamily is followed by a task, a family or an endsuite command.

endtask

This terminates a task definition. This is not strictly speaking needed, unless you want to add properties to the family containing the task or if you are using automatic generation to setup a suite. The example below highlights the use of endtask

family f
  task t1
  task t2
     edit ECFHOST c90
  endtask
  edit ECFHOST ymp8 # This variable is for family f!
 endfamily

The following achieves the same effect and is clearer:

family f
  edit ECFHOST ymp8
  task t1
  task t2
     edit ECFHOST c90
 endfamily
