I am just learning perl and have been doing some of the exercises in the
llama book.
I was doing page exercise one from page 57 and I was pulling out my hair
as to why it was not working and then I did something experimental and
got it to work. But to be honest I have no idea why it works.
I will attatch it to this email so that mayhap you can explain why it
does what it does.
Note: the think that I added was the double bang '!!'
I was previously using things like:
for ($i=0; $b[$i] != undef; $i++)
{
print STDOUT $b[$i];
}
and that seem logical but I was getting complaints such as..
"Argument "#stopped at 867\n" isn't numeric in ne at ./page57_1.pl line
9, <FILEIN> chunk 1544."
anyhow hope you can enlighten me as to all this hullaballooo ;-)
