in reply to DIFFERENCE BETWEEN VARIABLE

There is no difference, as far as perl is concerned, this is often a useful construct (albeit without the ' ' characters) which allows variables to be interpolated in strings next to other [A-Za-z_] characters:

$varname = 'poke'; print "${varname}mon\n";

Will output:

pokemon

while you could not have said:

print "$varnamemon\n";

as there is no such variable. You could avoid this by using . instead, but you'll see instances of the construct above.
