dbdownchanges the current workspace context to the workspace of the called M-file function when a breakpoint is encountered. You must have issued the
dbupcommand at least once before you can issue this command.
dbdown commands change the workspace context to each successively executed M-file function on the stack until the current workspace context is the current breakpoint. It is not necessary, however, to move back to the current breakpoint to continue execution or to step to the next line.
