Hi Erez
You may also be surprised to learn that all perl features are well documented.
You get the index with "perldoc perl", and the page referring to the one you
needed "perldoc perlvar".
I'd recommend reading all the online docs as they describe all the features of
the language.

Thanks, Erez. That's exactly what I was looking for. (told you
it was a noob question)

You can also read on all the special variables in Perl by typing
'perldoc perlvar' on your shell, or at
http://perldoc.perl.org/perlvar.html

Hi All,
I am about as noob as you can get so please forgive my complete naivete.
I have jumped into the world of perl with both feet and have gotten hung
up on a seemingly
trivial matter. In *NIX shell scripting, the variable $0 refers to the

Hi All
I have great issues
1) perl -e '$a=0.123451005;$a=sprintf("%.8f",$a);print"=$a\n";'
Output=0.12345101
2) perl -e '$a=5.123451005;$a=sprintf("%.8f",$a);print"=$a\n";'
Output=5.12345100
Here 1 one ging correct result but the second one wrong result
For second one result should be 5.12345

Since you cc'ed me I don't want to ignore this one though.
Yes, I know the dilemma of "let it die" or "would I be seen as ignoring a
point". I've purposely dropped you as a CC for this reason...
