Synergy DBL

Synergy DBL (Data Business Language) is a compiled, imperative programming language designed for business use. The language was originally called DBL; later it was referred to as Synergy Language; as of 2012 the official name is Synergy DBL. It is based on Digital Equipment Corporation’s DIBOL programming language.

DBL has an English-like syntax that was designed to be self-documenting and highly readable, but not verbose. The language is procedural and, since 2007 (version 9.1), object-oriented. Support for Microsoft’s .NET Framework was added in 2010 (version 9.5).

Code is split into two divisions (data and procedure) and uses a rigid hierarchy. The language includes a standard library consisting of 240 built-in subroutines and functions, 10 built-in classes, and 11 APIs that provide functionality such as access to XML from within DBL programs and sending and receiving data via .

Synergy DBL is cross-platform, with the current version running on all modern Windows platforms (Vista/Server 2008 and higher), as well as on HP-UX, IBM AIX, Oracle Solaris, several varieties of Linux, HP OpenVMS Alpha, HP OpenVMS I64 Integrity, and VSI OpenVMS for Integrity servers. Applications can be developed on one platform and ported to other platforms.

Traditional DBL is implemented as bytecode, which is executed by the Synergy Runtime. Synergy .NET programs are CLS-compliant and run under the .NET Framework.

DBL is distributed as part of a suite of programming tools sold as Synergy/DE Professional Series by Synergex International Corporation.

Synergy DBL is based on Digital Equipment Corporation’s DIBOL. DBL was developed by Digital Information Systems Corporation (DISC; the company name was changed to Synergex in 1996) in the late 1970s as a DIBOL alternative, targeting system integrators who combined DEC hardware with third-party peripherals. DIBOL ran only on DEC hardware, while DBL ran on most major business computer platforms.
