I could make the list a bit more clear. Now I gave the BGLC alias names, nut maybe the FS hex values that are listed in the SDK are more clear to some designers.
0DD6 - usrvar = 0312h
0DD8 - usrvr2 = 0314h
0DDA - usrvr3 = 0316h
0DDC - usrvr4 = 0318h
0DDE - usrvr5 = 031Ah
0DE2 - spar10 = 031Eh
0DE4 - spar11 = 0320h
0DE6 - spar12 = 0322h
0DE8 - spar13 = 0324h
0DEA - spar14 = 0326h
0DEC - spar15 = 0328h
0DEE - spar16 = 032Ah
0DF0 - spar17 = 032Ch
0DF2 - spar18 = 032Eh
I have no idea of they are 16 bit, how can I find that? I am not really into that kind of stuff, I found this with some trial and error.
I have tested most things in Fs2002 now, but I think (rather sure) that it should work from Fs98 till Fs2004.
I want to try to find some other scenery variables listed in the SDK as well. I will post it here when I can find them.
