/* Gary D. Riley */
/* */
/* Contributing Programmer(s): */
/* */
/* Revision History: */
/* */
/* 6.23: Changed name of variable exp to theExp */
/* because of Unix compiler warnings of shadowed */
/* definitions. */
/* */
/* 6.24: Renamed BOOLEAN macro type to intBool. */
/* */
/* 6.30: Module specifier can be used within an */
/* expression to refer to a deffunction or */
/* defgeneric exported by the specified module, */
/* but not necessarily imported by the current */
/* module. */
/* */
/* Added const qualifiers to remove C++ */
/* deprecation warnings. */
/* */
/* Converted API macros to function calls. */
/* */
/* 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. */
