DESCRIPTION

The recommended filename extension should be .z80 The file consists of header, address and data.

Header is 8 bytes long. It contains string Z80ASM (6 bytes - without trailing zero) followed by 0x1a character and linefeed character ( 0x0a ). The 0x1a character is to persuade DO$ viewers to stop viewing the file. The newline character terminates the header.

ADDRESS

Address follows the header as 2 bytes. These are interpretated as a 16-bit start address of the data(code) to load. The less significant byte comes first, most significant byte follows.

Data come after address. Data are raw compiled program. Length of data can be simply calculated to 'length of file - 10' bytes.
