Create a vector that associates a verb to a number.
Then create a second vector that associates a number to a verb command.
Sadly I was not able to store data or code directly in page 0 using CBM PRG Studio. If you know how I would like to hear you.
Now, you can define verbs like PUT o DROP and associate both with the number 3. Then, you associate number 3 to the DROP_SUBROUTINE.
I have no example code but it should be trivial using this adventure as source.
