There are huge numbers of results available for even the most trivial adjustment. These results can be displayed interactively by setting various output options using the OPTION: command. The various possibilities are described in some detail in §19.3. Every result that can be displayed interactively, as the adjustment is taking place, is retained and is available for display in exactly the same format at a later date by using the SHOW: command. This remains the case until the results of a new adjustment supercede the results of a former adjustment. It may be necessary or desirable to limit the output to a subset of the collection being adjusted. This is achieved by using the OPTION: command.
The great majority of results are also retained and available for use as further input. See, for example, §21.3 for standard adjustments, and in §21.5 for partial adjustments.
