Re: [pbmserv-dev] help with Get/Set Options in game.cpp

[Douglas Zander <dzander@solaria.sol.net>]

should this work?  (it doesn't when I tried it)

fencetype = GetOption("fences","thinfences");
gridtype = GetOption("grid","dots");

 it comes out to fencetype equal to ('osses')  (why???)

what exactly do you mean by "COPY the string..."???
