NAME

Language::Befunge::IP::lib::REFC - Referenced cells extension

DESCRIPTION

The REFC fingerprint (0x52454643) allows vectors to be encoded into and decoded from single scalar cell values.

Note that the internal list of references is considered shared among all IP's.

FUNCTIONS

new

Create a new REFC instance.

De/Referencing

$id = R( $x, $y )

Reference pops a vector off the stack, and pushes a scalar value back onto the stack, unique within an internal list of references, which refers to that vector.

($x, $y) = D( $id )

Dereference pops a scalar value off the stack, and pushes the vector back onto the stack which corresponds to that unique reference value.
