The debugging behavior of the GWAM can be controlled by the variable
*emu-debug*, which is normally set to nil to just run through the
WAM code. If the user wishes to have WAM debugging information, this global
variable may be set to t or :interactive by the RFE-command spy.
If *emu-debug* is set to :interactive, the following interactions commands may be used:
All control commands consist of one character. E,e Terminate and go to LISP. F,f Generate a fail. (Sometimes this command may cause trouble.) ? Output this Help-Menu. X,x Execute until program succeeds. S,s,newline Single step execution. V,v Output values before single step.
