Abstract
Most of the SIMULA-compilers adopt the EXTERNAL-declaration, although it does not belong to the standard of the language SIMULA. It has the form* EXTERNAL CLASS identifier list of external classes; or EXTERNAL [type] PROCEDURE identifier list of external procedures; By the EXTERNAL-declaration we can fall back upon classes and procedures already existing and include them into the new SIMULA program. The external procedures used may be written in programming languages different from SIMULA.
