concept asa always had an interest in supporting open source languages, db++ has had perl and tcl call interfaces for years now and uses tcl as its internal stored procedure language.
this extension relies on external client libraries so you have to have a db+ + client installed on the system you want to use this extension on.

assuming you're familiar with the concept of functions (if you're not, take a look at the chapter about functions), you'd assume that typing $c = foo() is essentially just like writing $c = 5, and you're right. functions are expressions with the value of their return value. since foo() returns 5, the value of the expression 'foo()' is 5. usually functions don't just return a static value but compute something.
but the truth is that there' s one additional value involved here, and that's the value of the assignment itself.
