Hidden features #7: Function expressions

Using the Function object, you can use any expression name and have it call a function. This means you can make Function.SomeExpression return whatever you like, and you can pass parameters to it too.

The .cap file attached shows an example of this (made in 0.98.9).

Wow.. even I'd forgotten that one.. That'll make a lot of things quite a bit simpler. Do you want to do a #8 on conditionals by the way, or should I?

Go for it.

Holy crap, that's awesome. I didn't even know that existed.

Nice . I remember this mentioned back in the day but I've only just recently started using the Function object so I'd forgotten all about it.

ah..thaaat's how you do parameters..thanks!

Wow, that is so much nicer than adding the parameters in the previous events. Nice!

And I was using "Add parameter" methods.... Very useful.

Can you make default parameter values?

No, that's not currently supported (but the Param expression returns 0 for any parameters that are not provided).

good to know!
