Inside a complex program, on WIN2k Server with 384Mb RAM I try to use
the trace(1) function that often crashes, or just exit the program in
unpredictable situations where no errors are detected in runtime.
Lines in view overlap each others skidding one step and doubling,
while you strive to follow a complex routine.. perhaps in presence
of certain comments or tab characters or I don't know what.
The trace(2) behaves better, but is not evenly legible; it is impossible
to fix a watchpoint and to know the content of a variable is mostly a trouble,
moreover is limited to the global sequence value into an unsuitable area.
The tab rendering put the program lines out of the window, spacing more than
they are set into my editor, so the code can result not enough visible.
The trace(0) does not answer in all situations.
No matter how many executions you would like to skip, you must stroke one key
at a time, or you risk to get executed more instructions than desired, as
the keyboard buffer gets all in advance.
Perhaps this feature was justified 10 years ago, but 24 DOS window rows are
unthinkable with the current technology and data problems; we need to watch
what's going on inside a program, if not to interact changing a value,
and in my experience this is so primitive and more limited than
the QuickBasic's was.
On the other side, Euphoria owns a superb language dynamic structure that,
far from the "easy to learn" lable, deserves that of extraordinarily advanced
for joining ease and potentiality. We should expect better accessories.
(Please, be patient with my speech.)

Just a further sample of an error detected some time ago and sent to Rob:

Thanks for reporting the problem.
I'll look into it.
Can you tell me which version of Euphoria you were using?
2.3? 2.4? 2.5 alpha?
