It is a convenience directive for defining least significant byte first two byte words, as the Z80 uses them. Multiple expressions, separated by commas, may be. ZASM is a compiler/assembler and monitor (including disassembler and debugger) for the Z80 CPU. It runs under Linux (probably also. Uses. The easiest way to put data directly into your program. Note that since the z80 processor is little-endian, loading into a bit register from.

At the start, the current address is set to 0. At the end of the program, it is allowed to use the “end” directive.

The filename is then read, until the ending quote, which is the same as the starting quote. Assembleurr after this directive is ignored. Incbin stands for “include binary”.

Using this directive more than once can be useful to create code which is to be executed adsembleur the same address, for example when the memory is mapped. It will seek in the output file and start overwriting previous output.


People have requested to be able to overwrite the generated output. It allows any binary data to be included verbatim into the output. This is mostly useful in combination with incbin.

The argument is given in the same way as for include. Multiple expressions, separated by commas, may be specified. Org only changes the zz80 idea of “where” it is. This can be used to put some comments at the end. The first non-whitespace character after the include directive is considered the starting quote. It is a convenience directive for defining least significant byte first two byte words, as the Z80 uses them.

There is no need to do this. With these directives it is possible to define new commands, which will output defined code.

Assemblejr the argument of seek is greater than the current output size, the file is extended with zeros. As in C but without thethis includes an other source file. Strings of bytes should be between double quotes.

It takes one argument, which must evaluate to a value in the first pass it may not use labels which are defined later. At the start of each page, the code can set the starting address to the mapping address.


Parts of the code assembleu be omitted using these conditional statements.

If val is omitted, it defaults to 0. Normally, the first directive in a program is org, to set the starting address. After this definition, it is possible to use the macro, like this: It allows the included binary to be “patched”. This sets the assembler’s idea of the current address. The previously defined pages are not overwritten. Almost any name is possible without escape characters, because of the quote rules.

Assembler directives

It reserves num bytes of space and initializes them to val. All definitions qssembleur be separated by commas. Code which is not assembled is checked for a correct command. Note that no code is generated by this directive, so if padding bytes are required, they must be inserted using defs.
