It is possible to get informations about the status of the computation of the functions of Chapter 2 of this manual.
‣ InfoPolenta | ( info class ) |
is the Info class of the Polenta package (for more details on the Info mechanism see Section Reference: Info Functions of the GAP Reference Manual). With the help of the function SetInfoLevel(InfoPolenta,level) you can change the info level of InfoPolenta.
If InfoLevel( InfoPolenta ) is equal to 0 then no information messages are displayed.
If InfoLevel( InfoPolenta ) is equal to 1 then basic informations about the process are provided. For further background on the displayed informations we refer to [Ass03] (publicly available via the Internet address http://www.icm.tu-bs.de/ag_algebra/software/assmann/diploma.pdf).
If InfoLevel( InfoPolenta ) is equal to 2 then, in addition to the basic information, the generators of computed subgroups and module series are displayed.
