DIBOL or Digital's Business Oriented Language is a general-purpose, procedural, imperative programming language that was designed for use in Management Information Systems (MIS) software development. It was developed from 1970 to 1993.
DIBOL has a syntax similar to FORTRAN and BASIC, along with BCD arithmetic. It shares the COBOL program structure of separate data and procedure divisions. Unlike Fortran's numeric labels (for GOTO), DIBOL's were alphanumeric;{{cite magazine |magazine=DEC Professional |date=November 1982 |page=70

History
DIBOL was originally marketed by Digital Equipment Corporation (DEC) in 1970.
The original version, DIBOL-8, was produced for PDP-8 systems running COS-300. The PDP-8-like DECmate II, supports the COS-310 Commercial Operating System, featuring DIBOL.{{cite news|url = https://archive.org/details/dibol_pro_tool_kit_v10|title = Introduction to DIBOL-83. Digital Equipment Corporation.|date = April 1984}}
DIBOL-11 was developed for the PDP-11 running COS-350 operating system. It also ran on RSX-11, RT-11, and from 1978 on RSTS/E. DIBOL-32 runs on VMS systems,{{cite magazine |magazine=Hardcopy

ANSI Standards were released in 1983, 1988 and 1992 (ANSI X3.165-1992). The 1992 standard was revised in 2002.
DIBOL compilers were developed by several other companies, including DBL from DISC (later Synergex), Softbol from Omtool,{{Cite book|url = https://books.google.com/books?id=w3IudMVoEusC|title = Computerworld|last = Enterprise|first = I.
