global
Perl
Something you can see from anywhere, usually used of variables and subroutines that are visible everywhere in your program. In Perl, only certain special variables are truly global--most variables (and all subroutines) exist only in the current "package". Global variables can be declared with our. See "our" in perlfunc.
