The Global Grouping Functions Container

The first time a set-variable is vivified (and comes to exist) it is assigned the dataset of a GADg object (returned by a function named GG-function), and GADg stands for Group-Algebraic-Data-groups. GG-functions are global grouping functions that are managed in the GG-container. All GG-functions start with the prefix gg followed by a word. One can type ggls at the ASPL prompt to list the GG-functions managed by the GG-container. If reloading is enabled, the ggls command will also reload the container before displaying the GGs functions. By default the reloading of GG-container is enabled, but it can be disabled by using the ASPL option -noreloadGG at its startup.

We use the term GGs to refer to the GG-functions. These functions are programmable and are located in their own directory that you can determine its location by issuing option -verbose when starting ASPL. Use the tilde command ~gg at the ASPL prompt to change the GG-container directory.
