Backward Compatibility

Definitions for the predicates that are now obsolete in ProXT 3.5 are provided in the file library(proxtbc). Many ProXT 3.1 programs will be able to run simply by adding the following declaration in the program:

     :- use_module(library(proxtbc)).

This module includes appropriate definitions for proxtCharPtrToString/2, proxtStringToCharPtr/2 and proxtGetDefaultCharset/1 to enable programs that use these in conjunction with xmString and xmText predicates to continue to work.
