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. 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, although it can also be used on other systems through
emulators.
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, and Unibol from Software Ireland, Ltd. Development of DIBOL effectively ceased after 1993, when an agreement between DEC and DISC replaced DIBOL with
DBL on
OpenVMS,
Digital UNIX, and
SCO Unix. ==See also==
