SIMPL(ID:7075/sim063)

Family of extensible structured languages

Victor Basili et al, University of Maryland at College Park, 1970s

Language of structured programming languages designed to be the opposite of PL/I (ie instead of having one language do everything, have a family of languages that did everything, with one language for each purpose) yet partaking of the same language form.

The highlights of the family were the SL/I language at the Langley Star computer (which vindicated the theoretical approach of extensibility and transportability), and the SIMPL-Q language (which became a staple for the US Navy).

Despite the family tree below, SIMPL-T was in fact created as an extension of SIMPL-X
