NAME
vars - Perl pragma to predeclare global variable names (obsolete)
SYNOPSIS
use vars qw($frob @mung %seen);
DESCRIPTION
NOTE: For variables in the current package, the functionality provided
by this pragma has been superseded by "our" declarations, available in Perl v5.6.0 or later. See "our" in perlfunc. This will predeclare all the variables whose names are in the list, allowing you to use them under "use strict", and disabling any typo warnings.Unlike pragmas that affect the $^H hints variable, the "use vars" and
"use subs" declarations are not BLOCK-scoped. They are thus effective
for the entire file in which they appear. You may not rescind suchdeclarations with "no vars" or "no subs".
Packages such as the AAuuttooLLooaaddeerr and SSeellffLLooaaddeerr that delay loading of subroutines within packages can create problems with package lexicals defined using "my()". While the vvaarrss pragma cannot duplicate the effect of package lexicals (total transparency outside of the package), it canact as an acceptable substitute by pre-declaring global symbols, ensur-
ing their availability to the later-loaded routines.
