I had thought @ was just an alias for the built-in Addr() function. (In classic / ISO Pascal, you can't get the address of anything, and '@' is a character substitute for '^'.) A quick search shows this: * https://wiki.freepascal.org/FPC_New_Features_3.2.0 FarAddr internal function Overview: There's a new i8086-specific internal function, similar to Addr(), called FarAddr(), which always returns a far pointer to the address of its argument. Notes: The built-in Addr() function and the @ operator return a pointer type (near or far), that depends on the memory model. When interfacing with DOS, BIOS and other 16-bit APIs, it is sometimes useful to be able to obtain a far pointer to a pascal variable or procedure/function, regardless of the selected memory model. Previously, you would have to use ifdefs, or do something like Ptr(Seg(x), Ofs(x)). Now, this can be replaced with the much nicer FarAddr(x). svn: r37629 _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
