While reading the Byte sieve article (Gilbreath 1981), I came across a language I have never heard of, ZSPL.
I suspected this was actually a specific version of another language, perhaps PL/1. However, the listing shows it most closely resembling Algol/Pascal.
Has anyone heard of this language before? It does not appear on the wiki nor the taxonomies of languages that I can find.
I have seen references to similar names, but they are not related: there is a zSPL system for programming the C64's SID and another for NonStop systems.
