SYMPL is an obsolete programming language developed by the Control Data Corporation for use on the CDC 6000 series computer systems in the 1970s and 1980s. It was based on a subset of CDC's version of JOVIAL, as an alternative to assembly language. A number of important CDC software products were implemented in SYMPL, including compilers, libraries, a full-screen editor, and major subsystems. SYMPL is a compiled, imperative, and procedural language. Compared to the Fortran of the day, SYMPL supports: • Strong data typing: All variables must be declared before use • Boolean variables • Variable bit width integers • "Status" variables • Data structures - Including "based" dynamically allocated structures • Structured programming constructs • Nested procedures • In-fix "bead" and character manipulation • A simple macro facility.
