Executes a subroutine declared by a sub declaration, and returns the value of the last expression evaluated in subroutine. subroutine can be an expression yielding a reference to a code object. The & may be omitted if the subroutine has been declared before being used.
Turns the object ref into an object in package. Returns the reference.
Returns an array ($package, $file, $line,...) for a specific subroutine call. caller returns this information for the current subroutine, caller(1) for the caller of this subroutine, etc. Returns false if no caller.
Deprecated form of &subroutine .
Substitutes a call to subroutine for the current subroutine.
Imports the named subroutines from module.
Cancels imported semantics. See use.
Designates the remainder of the current block as a package.
If expr is numeric, requires Perl to be at least that version. Otherwise expr must be the name of a file that is included from the Perl library. Does not include more than once, and yields a fatal error if the file does not evaluate to a true value. If expr is a bare word, assumes extension .pm for the name of the file.
Returns from a subroutine with the value specified.
Designates name as a subroutine. Parameters are passed by reference as array @_. Returns the value of the last expression evaluated.
Defines a setup block to be called before execution.
Defines a cleanup block to be called upon termination.
Ties a variable to a package that will handle it. Can be used to bind a dbm or ndbm file to a hash.
Breaks the binding between the variable and the package.
Imports semantics from the named module into the current package.
