## 5.8 Miscellaneous

### 5.8.1 `Quit.`

This command permits to quit Coq.

### 5.8.2 `Drop.`

This is used mostly as a debug facility by Coq's implementors and does not concern the casual user. This command permits to leave Coq temporarily and enter the Objective Caml toplevel. The Objective Caml command:

    #use "include";;

add the right loadpaths and loads some toplevel printers for all abstract types of Coq- section_path, identfifiers, terms, judgements, .... You can also use the file `base_include` instead, that loads only the pretty-printers for section_paths and identifiers. You can return back to Coq with the command:

    go();;

Warnings:

1. It only works with the bytecode version of Coq (i.e. `coqtop` called with option `-byte`, see page ??).
2. You must have compiled Coq from the source package and set the environment variable `COQTOP` to the root of your copy of the sources (see section 11.4).

### 5.8.3 `Set Silent.`

This command turns off the normal displaying.

### 5.8.4 `Unset Silent.`

This command turns the normal display on.

### 5.8.5 `Time` command`.`

This command executes the vernac command command and display the time needed to execute it.
