RE: about eval and stdin

Ok, I think I see the problem. I re-wrote your script a little (watch for line breaks), and you should be able to see what the problem is when you run it. Your substitution isn't doing what you think it's doing. In the future it always helps to add these kinds of "debug lines" when it seems

calling subroutine via hash

The following code calls only the first subroutine not the second. It seems to recoginize both subroutines but executes only the first one. Can anyone help me figure out how to get the code to call the second subroutine as well? Both subroutines when run as standard routines and not part of a has

You should be able to open a pipe to gpg. Here is something I've used on Windows (watch for line wraps): open(GPG,"| gpg.exe -q --passphrase-fd 0 -o \"$decrypted\" -d \"$encrypted\""); print GPG 'passphrase'."\n"; close GPG; -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL

One more thing: there are a few modules on CPAN that deal with this topic. Go to http://search.cpan.org and look up "precision" It looks like Math::FixedPrecision which uses Math::BigFloat is what you are looking for. -Original Message- From: Timothy Johnson Sent: Tuesday, January

Basic Math Problem

Hello, Here's my problem. I have the following lines coded in my perl program: $result = 1.00 - 9991.05; print "\n\$result = $result"; The result that is being printed is "8.950073" instead of "8.95". Can someone please tell me why perl acts this way. I am beginning to doub

Do you mean that you only want the first match, or that you only want the word "chen" when it's not preceeded or followed by other characters? You can use \b (word boundary) to make sure you got the whole word. $string =~ /\b(chen)\b/g; -Original Message- From: chen li [mailto:[EMAIL PRO

RE: about eval and stdin

I think when you include the parentheses in your pattern $1 is being set to the value inside the partentheses. It's as if you typed: if(/(dir)ectory/gi) which will set $1 to 'dir', which is probably not what you want. I think you can avoid this if you change the line to: if(/($pat
