-// Modifications:
-// 2003-11-06 JW: some corrections regarding missing spaces in generated code (e. g. "Property ")
-// 2003-11-06 JW: QuoteSnippetString implemented
-// 2003-11-08 JW: automatically add Microsoft.VisualBasic
-// 2003-11-12 JW: some corrections to allow correct compilation
-// 2003-11-28 JW: implementing code differences into current build of this file
-// 2003-12-10 JW: added "String." for the ChrW method because mbas doesn't support it without the String currently / TODO: remove it ASAP!
