Perl local Function
This function sets the variables in LIST to be local to the current execution block. If more than one value is specified, you must use parentheses to define the list.
Note that local creates a local copy of a variable, which then goes out of scope when the enclosing block terminates. The localized value is then used whenever it is accessed, including any subroutines and formats used during that block.
Following is the simple syntax for this function −
This function does not return any value.
Following is the example code showing its basic usage −
#!/usr/bin/perl -w local $foo; # make $foo dynamically local local (@wid, %get); # make list of variables local local $foo = "flurp"; # make $foo dynamic, and init it local @oof = @bar; # make @oof dynamic, and init it
