more thoughts on action

I see trees of actions. If, while and for statements are easily implemented as trees.

We can also distinguish between a set attribute and a make attribute: set only changes a value while make creates one if it does not exist. Set and get attribute would also check to see if the value starts and ends with a '%', in which case the value is the name of an attribute in the owner action. This would be a great means of handling return values, where the value returned would typically be a pathname.

These simple enhancements would give us the start of a powerful scripting language... in JOODBMS.
