This will print the contents of the variable $_, a new line, and the
contents of the hash element $blocks{$_} to the file handle FILE, which
presumably has been associated with a file using the open() function.

Equal to _what_ amount? Please be specific.

This should work. It is valid Perl. It generates a string (see above
for contents) and stores it in the variable $someData. Tell us why you
think it "doesn't work".

No, this is a syntax error.

Yes, you should post a complete, working, small-as-possible program
that demonstrates the problem you are having and what you think the
program should be doing that it is not.
However, you should post it to comp.lang.perl.misc, because this
newsgroup is defunct (and be sure and follow the guidelines for that
newsgroup).
Good luck.
