Either a function-object, a lambda-expression or a symbol with a function definition. If the function in question is not compiled (i.e. a lambda-expression) then it is first compiled using the function compile .
The size of the compiled code in bytes. An error is signalled if the argument to disassemble is not suitable.
This function views the machine-code of a compiled function definition in assembly language form.
The output from disassemble lacks useful information such as local and lexical variable names and symbol names. The representation of integers or characters or Lisp objects in general is not easily readable without detailed knowledge of the internals of the Lisp system and the host machine instruction set.
