No, you still wouldn't be able to do that since the RCX bytecode to play a
tone requires compile time constants as its arguments.
The scoping would let you put variables inside of tasks (hiding them from
other tasks), if you wanted...
task foo
{
int a;
// can use variable a
}
task bar
{
// can't see variable a
}
The inline stuff would let you write functions that took arguments - but
these arguments could only be used in places where variables are legal
(such as comparissons, and the Sleep() macro).

| Well, those are still cool new functions...I will keep wishing the RCX firmware allowed runtime evaluations instead of constants. Maybe LegOS does...does anyone know? Rich (URL) Message----- From: news-gateway@lugnet.com (...) (26 years ago, 22-Feb-99, to lugnet.robotics.rcx.nqc)
