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

|
|
84 sections, each of which has its own load address.</P

|
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
