Symbol Table Manipulation With *FRED
You can make b an alias for a
with
*b = *a. This
statement means that $a and $b
refer to the same variable, as do @a and
@b, and even filehandles and formats
a and b. You can also localize
*b inside a block with
local(*b), letting you have local filehandles,
formats, and other things. Pretty fancy stuff, but useful when you
need it.
