The MAXScript debugger implements the first half of a script development and debugging environment. It allows the main thread of 3ds Max to be suspended, the values of global and local variables to be examined and altered while the thread is not running, MAXScript commands to be executed from a command line, and the execution to be suspended using method calls from inside the MAXScript code. The debugger also lets you stop or continue the execution of the suspended code.
For detailed information about the MAXScript debugger, consult the MAXScript Help, available from Help menu
