Command line standard in/out

I can’t seem to find any mention of command line standard input/output… Console readln, writeln do nothing.
Help

What platform? writeLn should work on all platforms (but if you run on the mac you need a console attached to see it)

PC with Win 8.1. The properly compiled hello.pas outputs absolutely
nothing:

namespace std;

interface

implementation

BEGIN {hello}
VAR
i : integer;

 FOR i := 1 TO 10 DO BEGIN
     WriteLn('Hello, world.');
 END;

END {hello}.

Did you create a Console Application?

I get this:

(Set a breakpoint so I could see the output)

No. This is a program written on a text editor and compiled with the
command line compiler oxygene, ie., “oxygene hello,pas”
