17.2. Memory freeing operator

Lecture



  <deallocate descriptor statement> :: =
    DEALLOCATE DESCRIPTOR <descriptor name> 

Comment:

Executing this statement results in the release of memory from the previously allocated handle. After that, the use of the descriptor name is illegal in any statement other than ALLOCATE DESCRIPTOR.
