The whole use of types in Ada has kinda got me confused.

For example...

	the_volume := find_volume( aLength, aWidth, aHeight);

Gives me the error message on compile ...

	"array type required in indexed component"

This is NOT an array, it's a function call.

Heh, I guess I'll be hitting the books again.

Exceptions are something I plan on playing with soon. As soon as I got
all the basics worked out.

Thanks.
