Scratch

I do like this idea of yours. When I try to use formulas I always screw something up because I accidentally put a block in the wrong position due to scratch's "drag the block in" function. If you could just write it out and then scratch could create a variable out of it that can constantly change to fit your formula... Or you could make it so it remebers the formula in a block and lables it "formula1" or "formula2" and so forth. The it gets treated almost like a variable so you can insert it into almost anywhere.

I agree with you folks that creating long formuli in Scratch can be very difficult.  Part of the problem is the drag-and-drop interface.  It can be very hard to get a large lump of blocks to insert itself in a small opening in another block.  It would be nice to be able to switch to a select-and-click interface at times.  I'm visuallizing an interface where you would first select a chunk of blocks by clicking on it with your mouse.  The chunk would become highlighted but would not move.  You would then take your mouse and click on the spot where it was supposed to insert and it would then perform the action.

To summarize,  I am proposing improvements to the block interface rather than scrapping it entirely.

Interesting idea, I like it but I do not think it should be a block. Because It would not do anything in the game. It would only help you when scripting.
