The RCXCode programming system that comes with MindStorms is inherrently
limited in the ways you describe. That's really what this newsgroup/list is
all about; improving access to the true capabilities of the RCX hardware.
There are a number of ways to go from programming in Visual Basic, C through
to Smalltalk. You can find out about a number of available systems by
cruising around the MindStorms web ring at:

As far as I know most of the programming systems are text based (rather that
using a visual programming metaphore) but this shouldn't put you off since
they are significantly more useful than the RCXCode (IMHO). My suggestion
would be the Smalltalk interface at:
http://www.object-arts.com/Bower/Bot-Kit/index.html
not just because I wrote it, but also because the Smalltalk language is very
interactive and therefore so suitable for children to learn with.
