jb command
To display the contents of the registers (output is several screens long):
jb command
Displays memory beginning at a specified jump-buffer address.
jump-buffer-addr
is an address in memory
jump command
Continues execution of the current process at the specified line number or address.
The jump command changes the program counter to the specified location but does
not change the current stack frame or registers.

Caution. Use the jump command with care. It can result in program failure if the target
location depends on a state (such as registers) that has not been established.
