" If the secondary address isn't specified or is specified as 0 (e.g. LOAD "FILE",8), the file is saved/loaded from the BASIC memory area (which, on the C64, starts by default at $0801). If the secondary address is specified as a non-zero value (e.g. LOAD "FILE",8,1), the program is loaded starting from the address specified by the file itself (the PRG header, which is the first two bytes of the file)—this form of command is more common when loading machine code programs." From http://en.wikipedia.org/wiki/Commodore_DOS http://en.wikipedia.org/wiki/Commodore_DOS You are right in that auto loaders can be created using this method, but the ,1 means, load this file to the memory location specified by the first 2 bytes of the file.
