Algol 68-r

algol 68-r
A restriction of ALGOL 68 permitting one-pass compilation, developed at the Royal Signals Radar Establishment, Malvern, Worcester, UK in April 1970.
Identifiers, modes and operators must be declared before use. There is no automatic proceduring and no concurrency. It was implemented in ALGOL 60 under GEORGE 3 on an ICL 1907F.
