ASSEMBLEUR Z80 PDF

The previously defined pages are not overwritten. Z80 Software Development Tools Everything after this directive is ignored. Otherwise it is not touched, which means that if you use these directives, a successfull assembler execution does not imply that all the code is correct. It takes one argument, which must evaluate to a value in the first pass it may not use labels which are defined later. This can be used to put some comments at the end.

Grokazahn This can be used to put some comments at the end. It allows any binary data to be included verbatim into the output. If val is omitted, it defaults to 0. Using this directive more than once can be useful to create code which is to be executed assemnleur the same address, for example when the memory is mapped. There is no need to do this. Note that no code is generated by this directive, so if padding bytes are required, they must be inserted using defs.

The previously defined pages are not overwritten. If the argument of seek is greater than the current output size, the file is extended with zeros.

DWL G PDF In the following example, the output contains 4 bytes: At the start of each page, the code can set the starting address to the mapping address. At the start, the current address is set to 0. It will seek in the output file and start overwriting previous output. It takes one or two arguments, num and val.

Almost any name is possible without escape characters, because of the quote rules. It reserves num bytes of space and initializes them to val. With these directives it is possible to define new commands, which will output defined code. All definitions should be separated by commas. Otherwise it is not touched, which means that if you use these directives, a successfull assembler execution does not imply that all the code is correct. As in C but without thethis includes an other source file.

It takes one argument, which must evaluate to a value in the first pass it may not use labels which are defined later. Parts of the code can be omitted using these conditional statements. After this definition, it is possible to use the macro, like this: This is what seek is for. This is mostly useful in combination with incbin. Everything after this directive is ignored.

Normally, the first directive in a program is org, to set the starting address. People have requested to be able to overwrite the generated output. It is a convenience directive for defining least significant byte first two byte words, as the Z80 uses them.

Code which is not assembled is checked for a correct command. Multiple expressions, separated by commas, may be specified. The first non-whitespace character after the include directive is considered the starting quote. The argument is given in the same way as for include. Related Articles
