The best way of seeing what the interpreter makes of all yuor commands (apart
from examining the parser source), is by using the debugging mode, and typing
"actions on". You can then type in whetever you want, and you get to see what
actions are produced. If these are incorrect, or produce an error, then you
can add your own extensions to the grammar.
