Display and Control Commands

The following commands display and control the status of kadb(1M):

$b

Display all breakpoints 

$c

Display stack trace 

$d

Change default radix to value of dot 

$q

Quit 

$r

Display registers 

$M

Display built-in macros 

`$c' is useful when a breakpoint is reached, but is usually not useful if kadb(1M) is entered at a random time. The number of arguments to print can be passed following the `$c' (`$c 2' for two arguments).
