4 The MLWorks Interactive Environment Library
4.4 Debugging interface: the Debug structure
There are two interfaces to the debugger: the GUI version and the TTY version. See the MLWorks User Guide for details. The functions in Debug invoke whichever of the two is appropriate to the context used.
To use the debugger on a function, ensure that the function has been compiled with debugging mode on and, usually, with optimizing mode off.
