[TYPO3-dev] how to save inputs in own BE-Module?

[bernd wilke]

I just write a new BE-module where an editor can select some values and 
an acttion will result.
adding a second select-menu (like the function-menu) was easy and from 
one visit to another all values were saved for an editor (but I don't 
know which functions are used).

now I want the user to select some checkboxes where he can select 
multiple options (this is done a little bit unusual bitwise in one 
integer value), but all entries to the checkboxes are lost as far as the 
user starts the BE-module again or just selects another page.

how can I save the userselection for these checkboxes in a TYPO3 way?
