The TTY Inspector

If X is unavailable, a terminal inspector is invoked. The TTY inspector is a crude interface to describe which allows objects to be traversed and maintains a history. This inspector prints information about and object and a numbered list of the components of the object. The command-line based interface is a normalread-eval-print loop, but an integer n descends into the n'th component of the current object, and symbols with these special names are interpreted as commands:

U
Move back to the enclosing object. As you descend into the components of an object, a stack of all the objects previously seen is kept. This command pops you up one level of this stack.

Q, E
Return the current object from inspect.

R
Recompute object display, and print again. Useful if the object may have changed.

D
Display again without recomputing.

H, ?
Show help message.
