normal use. They are:
@table @var
-@item arglist
-The list of argument symbols.
+@item argdesc
+The descriptor of the arguments. This can either be a list of
+arguments, as described in @ref{Argument List}, or an integer encoding
+the required number of arguments. In the latter case, the value of
+the descriptor specifies the minimum number of arguments in the bits
+zero to 6, and the maximum number of arguments in bits 8 to 14. If
+the argument list uses @code{&rest}, then bit 7 is set; otherwise it's
+cleared.
+
+If @var{argdesc} is a list, the arguments will be dynamically bound
+before executing the byte code. If @var{argdesc} is an integer, the
+arguments will be instead pushed onto the stack of the byte-code
+interpreter, before executing the code.
@item byte-code
The string containing the byte-code instructions.
@code{backward-sexp}.
