13.3 Debug Mode

There are two additional support functions that allow the user to interrogate where in the execution of a script Octave entered the debug mode and to print the code in the script surrounding the point where Octave entered debug mode.

— Loadable Function: dbwhere ()

Show where we are in the code

     
     
See also: dbclear, dbstatus, dbstop.

— Loadable Function: dbtype ()

List script file with line numbers.

Debug mode equally allows single line stepping through a function using the commands dbstep and dbnext. These differ slightly in the way they treat the next executable line if the next line itself is a function defined in an m-file. The dbnext command will execute the next line, while staying in the existing function being debugged. The dbstep command will step in to the new function.
