- Opcode: 0x00
- Short name: RET
- Long name: Return from request / Halt
When an entity's script is being executed as part of a request (function call), the return opcode will cause current execution to halt and return to whatever the entity was previously executing (at some lower priority). If the execution was requested via a synchronous call (REQEW or PRQEW), the completion of execution is also signalled to the calling entity which can resume execution.
If return is used when executing at base priority, execution will simply halt. This is what happens in the entry scripts.
