Why is TRACE an EXECUTABLE Statement at all?

[ThSITC]

Hello there,

    1.) I don't know whether I should discuss this topic here *or* in
[hidden email]. Please advise! :-)
    2.) The issue is as follows:

When, after a leading TRACE ALL, after a METHOD Directive (clause), and
a couple of ordinary
statements (clauses), including a couple of valid RETURN's, a TRACE OFF
is encountered,
then the current NetRexx Compiler complains:

Clause cannot be reached

if all branches in a conditional statement already do contain the proper
RETURN statement (Clause)

I personally do think, TRACE should be regarded and handled as a
Directive (as I call them)
*and NOT* as an ordinary clause :-)

Kind regards from dark Vienna,
Thomas Schneider.

Hi,

it's not a directive, although it feels a lot like one. But the fact
that it isn't makes the following possible:

if debug then
   trace results
else
   trace off

I love this feature, and I bet there's more of us out there.

It's fine the way it is.

cu,

Patric
