I doubt anyone here can replicate your problem. Can you please show us the minimal amount of code YOU can run that produces this problem?

You may have a problem with quotes matching in unexpected ways. As japhy says - show us some code! You're just jealous cause the voices are only talking to me. No trees were killed in the sending of this message. However, a large number of electrons were terribly inconvenienced.	[reply]

A minimal code sample that reproduces the problem is essential if you're going to get any useful help. That said, the most likely explanation, just to expand on what the above poster already said, is that you've placed your variable in single quotes in your `print` statement. One difference between single and double quotes is that double quotes allow "interpolation"; stated roughly, they substitute the values of variables for their names. To get into the nitty-gritty of it, you should read `perldoc perlop`, especially the section on "Quote and Quote-like Operators." BCE --Your punctuation skills are insufficient!	[reply]

No one can say for sure unless they see your code, but to me it seems like a classic example of global/local variables. -imran	[reply]

I tried what I could of your code. First, it's not clear to me what you intended with your double quotation mark in the s/// function. Was it your intent to replace quotation marks by "-eee-"? When I ran it both ways (printed to STDOUT and to a file), the results were the same - the substitution was performed, and I got "-eee-" both on the screen and in the file My guess is that you've somehow eliminated the bug while trying to show us the problem. See if you can come up with a short script that cuts out all the unnecessary stuff, but that still produces the bug. I've found that most of the time, when I try to reduce the code to the bare minimum that still has the bug, I wind up figuring out what the problem is myself - the bug suddenly shows up very clearly, once all the other stuff has been removed. Finally, when you're showing code, use the <code> tags. They automatically format the code into legible form.	[reply]
