Business Application Language (BAL) refers to one of many offshoots of theBASIC language and should not be confused with IBM's well-establishedBasic assembly language.
Business Application Language was originally defined byHoneywell in 1973 and the major diffusion was in their system '80-'90 inEurope with the work of French firmPrologue S.A. that used BAL for programming on their proprietary Operating System (Prologue).
In 1986 the language was ported to theUnix platform byGuyPes. The first development environment, named Balix, are distributed starting in 1988 in Italy and France. A different evolution path was made by Prologue S.A., named ABAL, in 1992.
The evolution of Balix, developed inItaly, is calledB2U[1] (an acronym for Business under UNIX) developed byGuyPes, and are used for a Banking Information System that are used by one hundred banks in Italy.
