Handling GQEs

SPECTRA stores data in a linked list called a queue. More informations about the data structure is provided in appendix . This section summarizes those commands that operate on the queue elements (GQEs).

 compress
Garbage collection: Deleted queue elements are removed from the memory (sec. 15.3.13). Mind that the DELETE command removes them only from the queue.

 copy
Copies a queue element to a different location (sec. 15.3.14).

 create
Creates a new queue element (sec. 15.3.16).

 delete
Deletes one or more queue elements (sec. 15.3.20).

 preserve]
Prevents a GQE from being deleted. Preserved GQEs are written to a dump file at the end of a session and automatically restored during the startup of the next session (sec. 15.3.52).

 rename
Renames a GQE (sec. 15.3.58).

 reset
Start from scratch. After a reset, also symbols are deleted (sec. 15.3.59).
