These are very basic questions, which any good perlbook will deal with.
(I'd advise 'learning perl' by randal schwartz).
now for your answers:
1: that's called 'autoflush', print right away rather then buffering
2: undefine a variable (ie, make it empty)
3: they're called hashes, and => makes '' unnecessary in most cases.
for more elaborate answers, read the tutorials i wrote about just this at
http://japh.nu
you'll want the data types tutorial and the perlvar tutorial
