demos between levels and parms

[Nahuel]

Hello, when I reproduce a movie - demo between levels I add to the stuffcmd of the demo the lines "MAP themap". This works fine, but when the player changes of map the parms return to zero. Because necessary I have to use the command "map" not the "changelevel"(as if it began in the map "start" of the normal quake).
I thought that there could keep the items that the player takes in the FRIK-FILE. Or in another external line. is this possible? how can I use the FRIK FILE to do this? are there examples?

Thank you!
