An argument passing convention where the actual argument isa variable V whose value is copied to a local variable Linside the called function or procedure. If the proceduremodifies L, these changes will not affect V, which may also bein scope inside the procedure, until the procedure returnswhen the final value of L is copied to V. Undercall-by-reference changes to L would affect V immediately.Used, for example, by BBC BASIC V on the AcornArchimedes.
