Scope of the TRACE statement

[ThSITC]

Hello all,

    I think I am meanwhile very well known in this community to raise
*unwanted* and *unneeded* discussions.

Nevertheless, I'm trying it again!

Currently, the TRACE statement becomes effective when executed.
e.g. TRACE ALL sets (internally) the TRACE Generation flag.
... and does then generate TRACE Code.

As far, as excellent.

However, after many tries, and pitfalls as well, I *personally* do
*think* that the
effect of a TRACE statement (I do call TRACE a directive, NOT a Verb, by
the way)

SHALL be SCOPED!

e.g. when I do have a sourc code of

method GetExpression() public returns int
    TRACE all

... then:

The TRACE should TERMINATE after the return of this method.

The current implementation in NetRexxC traces everything after the
TRACE in the example code, i.e. the intenal NetRexxC compiler flags
are set in a way, that they do remain effective aftr isuing the TRACE.

This shall and should be changed in the next release of NetRexxC, IMHO!

Sleep well, al together!

Crazy Uncle Thomas (Massa Thomas, as my Egyptian friends here in Venna
do call me :-)).

That would go contrary to the existing NRL3 document:

Within methods, the trace instruction changes the trace setting or variables tracing when it is
executed, and affects the tracing of all clauses in the method which are then executed (until changed
by a later trace instruction).

This shall and should be changed in the next release of NetRexxC, IMHO!

Why not simply put a TRACE OFF statement at the end of your methods?

Sleep well, al together!

I believe that my wife would prefer that I sleep with her, at least most of the time.  Go ahead and start without me.

Tom.
