The [[built-in function (Perl)|built-in function]] {{perlfunc|my}}() in [[Perl]] creates a variable that is local to the current scope. That is, it is defined:
* within the current set of curly braces {}
* within any further curly braces that are within that current set (as one would expect)

If a variable of the same name exists outside of the current scope, {{perlfunc|my}}() creates a new variable and ignores/preserves the older variable. ''Query: is there a way to access the older variable from inside this scope?'' The older variable is once again accessible when execution leaves the current scope.

{{perlfunc|my}}() is very similar to {{perlfunc|local}}(), except that {{perlfunc|my}}() does not do dynamic scoping. {{perlfunc|my}}() is generally recommended over {{perlfunc|local}}(). (You may hear the saying "Don't use local()" from experienced Perl programmers.)
==Versions==
* {{perlfunc|my}}() was introduced in Perl 5.
==Examples==
* my($avar,$anothervar);
* my($arg1,$arg2) = @_;
* my(%hashvar);
* my %anotherhash;
* my $justonevar;
* my @anArray;
