for DEC Algebraic Language (no relation to DEC Author Language)

or perhaps (according to Bennett 1976) for DEC Compiler, Assembler, and Linking Loader (though that would be DECCALL)

Hybrid of DEC assembler and Algol 60, used in the Decision Sciences Lab ESD and written by ICS.

Like Algol 60, it lacked I/O which was rectified in different ways (hence different dialects)
