Other Changes

• MacOS X: Support for the native Aqua version of Tcl/Tk (8.4.2). See Tcl/Tk Notes. The interaction between SICStus Tcl/Tk and the Mac OS X dock is still rather primitive. There is, for instance, no way to specify an icon or to handle the dock Quit command.
• The Visual Basic interface now pass UNICODE characters to PrologOpenQuery, PrologOpenQuery, PrologQueryCutFail, PrologGetString, PrologGetStringQuoted, and PrologGetException. This improves the handling of international characters (characters outside the 7-bit ASCII range).

  This change should not affect your Visual Basic code but the vbsp.bas file has changed. This change also affects those that use the vbsp.dll from other languages than Visual Basic.

  Characters outside the 7-bit range may not work under Windows 95.

  The library/vbsp/examples/train/ sample project now use characters outside the 7-bit range.

• A better string hash function yielding faster atom lookup.
• The open_hook of the default wcx-box no longer ignores the option argument. In particular it is now posible to read and write files using ISO 8859/1 (Latin 1) even if SP_CTYPE is utf8; see WCX Hooks.
