2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues.
2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)
Binary file
A CoCo binary file can contain sheer data or one or more executable machine language programs. They can be loaded into memory from disk using the LOADM command or from tape using the CLOADM command. Included in the format is the load address of the binary as well as an execution address. They may contain multiple loadable sections each having its own load address. A section starts with a five byte long preamble of which the first byte is $00, the following two bytes specify the length of the data block to be loaded, and the last two bytes specify the start address in RAM the data block is to be loaded at. This is then followed by the actual bytes comprising ML code and/or any data. The data block can be followed by another preamble to a new section with more data/code or is terminated with a postamble. The postamble is also five bytes in length, with the first one being $FF, the next two being $00, and the last two forming the execution address for the ML program in the binary file, if any.
| 00 | length | start address |
