DBAUTO DBAUTO Control Dbauto Functionality

Usage

The dbauto functionality in FreeMat allows you to debug your
FreeMat programs.  When dbauto is on, then any error
that occurs while the program is running causes FreeMat to 
stop execution at that point and return you to the command line
(just as if you had placed a keyboard command there).  You can
then examine variables, modify them, and resume execution using
return.  Alternately, you can exit out of all running routines
via a retall statement.  Note that errors that occur inside of
try/catch blocks do not (by design) cause auto breakpoints.  The
dbauto function toggles the dbauto state of FreeMat.  The
syntax for its use is

   dbauto(state)

where state is either

   dbauto('on')

to activate dbauto, or

   dbauto('off')

to deactivate dbauto.  Alternately, you can use FreeMat's string-syntax
equivalence and enter

   dbauto on

or 

   dbauto off

to turn dbauto on or off (respectively).  Entering dbauto with no arguments
returns the current state (either 'on' or 'off').
