A trace() Christmas gift.

Some tricks that could be not well known and used.

1. When in the manual trace() mode, you can Double-click any variable name,
or highlight it with the cursor, if you mind some external delimiter to be
added,
then Right-click to copy that string.

2. after pressing the '?' key for to obtain its value, just Right-click, no
matter
where the cursor is, to enter the variable name and press Enter for the answer.

3. It's very easy to copy any text from a DOS window and paste it into an editor
frame.
Simply highlight the area you are interested to and Right-click to copy; 
this you can paste where you want.

"Dulcis in fundo"

4. When in the local trace() mode - that is for instance a trace(2) set inside a
procedure() -
you meet the call to another procedure() or function(), this will be silently
executed,
without let you see what happened therein.
To watch these, you should put another trace() command there and so on..

If you set the trace option in your main procedure will trace *everything*, 
once it is turned on, but into a large project this could make "impossible" to
use it;
to limit the tracing inside minor routines or loops can sometime drive a
programmer.. to give up.

Well, put a single trace(1) or trace(2) where you want to start your trip and,
whenever the cursor
stands over any routine that you want to explore press Ctrl-Enter; this way you
can even walk
through the libraries, if needed.
Being the real solution to both the above limitations, this new feature makes
the trace() very powerful.


Merry Christmas to all the Euphorians :o)
