TCO

Opens the global tracing console -- a standard console window that can be
moved and resized by the user and will have all of the standard input
controls of the user-shell specified for the system.

Trace output generated by currently active ARexx scripts will be diverted
immediately to the tracing console.

The tracing output itself is controlled by the  TRACE  instruction, the
 TRACE()  function, and by the  TS  and  TE  commands.

If a trace request is issued when the trace console is not open, ARexx
will attempt to output the trace to a shell. Without the trace console,
however, ARexx will usually have no place to send trace output from a
macro started within an application program.

The trace console is opened as the logical device  STDERR . If the trace
console is open, an ARexx program may send output to the window with the
instruction { CALL  WRITELN  STDERR, <output> }. The instruction { PARSE
 EXTERNAL  <template> } will retrieve user input from the trace console
rather than the CLI.
