Or alternatively
for c := Low(node) to High(node) do
Writeln(node[c]);
Or:
for n in node do // n is a var declared as String
Writeln(n);
Note: you can't modify array elements in the for-in-statement, as the
iterator variable merely contains a copy; however if the iterator variable
is a pointer type (or class/interface instance) then you can modify the
element's contents of course, but not the element itself (e.g. changing the
pointer value).
