13.4 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.

— Command: dbstep n
— Command: dbstep in
— Command: dbstep out

In debugging mode, execute the next n lines of code. If n is omitted execute the next line of code. If the next line of code is itself defined in terms of an m-file remain in the existing function.

Using dbstep in will cause execution of the next line to step into any m-files defined on the next line. Using dbstep out with cause execution to continue until the current function returns.
