#t if obj is a stack frame.
Return the previous frame of frame, or
frame is the first frame in its stack.
Return the procedure for frame, or
#f if no
procedure is associated with frame.
Return the arguments of frame.
Accessors for the three VM registers associated with this frame: the frame pointer (fp), instruction pointer (ip), and stack pointer (sp), respectively. See VM Concepts, for more information.
Accessors for the three saved VM registers in a frame: the previous frame pointer, the single-value return address, and the multiple-value return address. See Stack Layout, for more information.
Accessors for the temporary values corresponding to frame’s procedure application. The first local is the first argument given to the procedure. After the arguments, there are the local variables, and after that temporary values. See Stack Layout, for more information.
Display a procedure application frame to the output port port. indent specifies the indentation of the output.
(system vm frame) module defines a number of
higher-level introspective procedures, for example to retrieve the names
of local variables, and the source location to correspond to a
frame. See its source code for more details.
