This program can be complied by Cobra, can be executed by Windows, but not fails when Cobra executes it:

class Hello

def main is shared
print 'hello, world.'

D:\CobraProjects\HelloWorld>cobra -compile HelloWorld.txt

Cobra debugging tips:
To get file name and line number information for the stack frames, use:
cobra -debug foo.cobra
To get a post-mortem, HTML-formatted report with more details about your obj
ects:
cobra -debug -exception-report foo.cobra
For even more information, try:
cobra -debug -exception-report -detailed-stack-trace foo.cobra
Or use the abbreviations:
cobra -d -er -dst foo.cobra

Cobra debugging tips:
To get file name and line number information for the stack frames, use:
cobra -debug foo.cobra
To get a post-mortem, HTML-formatted report with more details about your obj

That's neat. What's your output with verbosity turned on?:

cobra -v:2 -d HelloWord.txt

Also, try renaming your program to HelloWorld.cobra because, honestly, I've never once run a Cobra program with an extension other than ".cobra". I therefore suspect that is the problem.

Of course, you were right about the extension..works as .cobra. Follow up:

===================================================================================
1. With the .cobra extension, it prints the output 3 times. (Actually, with the .txt extension, it fails 3 times, too)

D:\CobraProjects\HelloWorld>cobra HelloWorld.cobra
hello, world.
hello, world.
hello, world.

===================================================================================
2. Here is debug output using .cobra (to explain the triple output?):

The triple output is amazing; I haven't seen anything like it. Are you using a cobra.bat that you made? Could it have extra lines in it, maybe from a copy and paste with too many pastes?

Does anyone else experience Cobra running in triplicate?

Btw for really long output like that, I think an attachment(s) would work best. These are available under the text box that you compose your messages in.

Wow, how I ever managed that I don't know...ya, triple entries in the.bat. Hope you didn't chase that one more than a minute. Sorry 'bout the huge paste...I'll take the time to review this board's capabilities before posting again.

Best regards,
Shadow
