Is it possible to access the list of slides visited from the user's last session?

My scorm has multiple sections. I'd like to have the scorm remember which sections have been completed when the user comes back to a new session with the scorm.

The sections functionality can be achieved using user variables, but user variables aren't remember between sessions so the user would be forced to go thru all the sections over again, starting the scorm from the beginning.

If there's a way to get a list of all the slides that the user has visited in their previous sessions, then the sections functionality can work as intended.

Is this possible? It seems that the TOC shows all of the slides that the user has visited in their previous sessions, so it seems the LMS is keeping a "slides visited" list\array somehow.

The sections functionality can also be workable if it were possible to record and remember any single variable (string, or integer\float) between sessions. For instance, if there were 5 sections then a single integer could be used to record which of the 5 sections had been completed previously, encoded as a value between 1-32 (32 = 2^5 = {no, yes}^{5 sections}). Similarly, a string could hold the information just as easily (string = "yynny" = sections 1,2,5 complete and sections 3,4 incomplete).

Any thoughts or information would be quite appreciated,

Thank you.
