/*************************************************************/
/* Purpose: */
/* */
/* Principal Programmer(s): */
/* Gary D. Riley */
/* */
/* Contributing Programmer(s): */
/* */
/* Revision History: */
/* */
/* 6.24: Added environment parameter to GenClose. */
/* Added environment parameter to GenOpen. */
/* */
/* Renamed BOOLEAN macro type to intBool. */
/* */
/* 6.30: Changed garbage collection algorithm. */
/* */
/* Removed conditional code for unsupported */
/* compilers/operating systems (IBM_MCW and */
/* MAC_MCW). */
/* */
/* Added code for capturing errors/warnings */
/* (EnvSetParserErrorCallback). */
/* */
/* Fixed issue with save function when multiple */
/* defmodules exist. */
/* */
/* Added const qualifiers to remove C++ */
/* deprecation warnings. */
/* */
/* Converted API macros to function calls. */
/* */
/* Fixed linkage issue when BLOAD_ONLY compiler */
/* flag is set to 1. */
/* */
/* Added code to prevent a clear command from */
/* being executed during fact assertions via */
/* Increment/DecrementClearReadyLocks API. */
/* */
/* Added code to keep track of pointers to */
/* constructs that are contained externally to */
/* to constructs, DanglingConstructs. */
/* */
/* 6.40: Removed LOCALE definition. */
/* */
/* Pragma once and other inclusion changes. */
/* */
/* Added support for booleans with <stdbool.h>. */
/* */
/* Removed use of void pointers for specific */
/* data structures. */
/* */
/* ALLOW_ENVIRONMENT_GLOBALS no longer supported. */
/* */
/* UDF redesign. */
/* */
/* Modified EnvClear to return completion status. */
/* */
/* File name/line count displayed for errors */
/* and warnings during load command. */
