1. crash_message()

Rob, A small addition to the ever growing wish list: can we have a routine that would return the current position of the interpreter within the source. Just the file name and the line number. Alternatively, would it be possible to extend the crash_message() routine to include this sort of information. As it is now, I have to combine the crash_message() with something silly like ? 1/0 to induce a traceable error. Otherwise it is quite painful, especially with multiple includes and thousands of lines in each, to locate offending sections of the code. Or am I missing something, is there a better way of doing the same? jiri

Sorry, guys, this is one of those days, I should not be allowed anywhere near a terminal... What I really meant in my previous message was, that I would prefer to use the interpreter location routine with a simple abort(), instead of artificially inducing silly errors to get the location through the standard error mechanism. jiri

I'll consider it. I guess it would let you implement a kind of C assert() statement. e.g. assert(x < 100) where you print a message with the offending file and line number when the assert fails. Of course, procedure assert(integer x) if not x then ? 1/0 end if end procedure would be almost as good. Regards, Rob Craig Rapid Deployment Software http://www.RapidEuphoria.com

I think assert is a wonderful construct as it assists in the development of an application. Also there is a logical way to deactivate them without assert and reactivate them with assert These would increase the ability for library developers to create good error checking, the current method of returning an error indicator often doesn't work. Which is why C++ requires new to throw an exception. I doubt it would be hard to implement and it would give so much to the programmer.
