80 >A DECB binary is compatible with the LOADM command in Disk Extended
81 Color Basic on the CoCo. They are also compatible with CLOADM from Extended
82 Color Basic. These binaries include the load address of the binary as well
83 as encoding an execution address. These binaries may contain multiple loadable
84 sections, each of which has its own load address.</P
85 ><P
86 >Each binary starts with a preamble. Each preamble is five bytes long. The
87 first byte is zero. The next two bytes specify the number of bytes to load
88 and the last two bytes specify the address to load the bytes at. Then, a
89 string of bytes follows. After this string of bytes, there may be another
90 preamble or a postamble. A postamble is also five bytes in length. The first
91 byte of the postamble is $FF, the next two are zero, and the last two are
92 the execution address for the binary.</P
