Thats &4b50 (Hex) to load the header of a file put its file type at &4b00 and the 10 char filename at &4b01 then use hook code 129 to load the 48 byte header at &4B50 now you can load the file at page B offset HL (location C, &8000-BFFF). C is pages and DE modulo 16384 bytes to load. Use hook code 130 in location B (&4000-&7FFF) to load the file Also HMPTR (port 251) is not restored. To set DOS error trapping set the address of your error code at &5BC0. Make sure you set &5BC3 to 0 after a error has occured and &5BC0 to 0 (word) when error trapping is no longer needed.
