The APL:9SPlus:2E System for the Macintosh: an overview
Edward R. Myers · 1987
The APL*PLUS System for the Macintosh™ is a full-featured APL interpreter that integrates the Macintosh user interface style into a standard APL*PLUS System environment. An overview of these Macintosh-specific features along with a comparison of the capacity and performance of the APL*PLUS Mac System to other APL systems suggests that APL applications that are highly interactive, require large workspaces, and need advanced graphics are best implemented on the Macintosh.
