=={{header|Z80 Assembly}}==
The Z80 itself has no way of enforcing immutability. Code and/or data are only immutable if they exist in ROM (read-only memory.) Typically, Z80-based computers will copy the contents of a floppy disk or CD-ROM to internal RAM and execute it there, whereas ROM cartridges are directly mapped into the Z80's address space and executed in ROM. As a result, there is no special syntax for enforcing immutability, as it relies entirely on where the code/data is located and what medium it is executed from.
Side note: Trying to write to ROM at runtime will simply have no effect, and will not raise any kind of hardware exception or segfault.
