Others have replied to the issue at hand, but here's a general hint:
Some people (like me) only scan newsgroups occasionally, when we have
a minute, and at least I personally find it annoying when the subject
line of an article reads "help" or "I have a problem" or "How to solve
this problem?" -- it means that I have to retrieve that article and
read through it before I even know whether I am qualified to answer
it. Maybe it's about something I don't understand myself, and then it
seems it would be polite to give me at least a hint what you're
talking about in the subject line so I don't have to read your article
in the first place.
Had you chosen the error message itself as a "subject" ("Loop limit
expression too large for loop variable type") every reader of the
group would've known what your postis about and whether they know the
answer.
Even better: If you copy/paste the full error message into the
google-news interface
at http://groups.google.com/groups?group=comp.lang.idl-pvwave
you'll get the answer to your problem without even having to post. I
find this to be a good first step with all kinds of computer-related
questions, as it gives me a bit of an idea how common the problem at
hand is -- have others encountered it, how did they proceed, what
advice was given to them etc. Even if my question can't be answered
that way, I often find a useful hint that helps me solve my problem
myself.
