Make 'foo' local to the block. Otherwise, the
second time you run Restart, foo still has the
value "q". So the while immediately terminates.
Restart():= block([foo], while (foo # "q") do
(foo: read("Enter a number to continue, \"q\" to quit. "),
print(" you entered ",foo)
),
print(" Bye!")
)$
This time, I tested the code; it seems to work:
(%i1) load("q.mac")$
(%i2) Restart();
Enter a number to continue, "q" to quit. 0;
you entered 0
Enter a number to continue, "q" to quit. "q";
you entered q
Bye!
(%o2) Bye!
(%i3) Restart();
Enter a number to continue, "q" to quit. sqrt(2);
you entered sqrt(2)
Enter a number to continue, "q" to quit. 42;
you entered 42
Enter a number to continue, "q" to quit. "q";
you entered q
Bye!
(%o3) Bye!
