Thanks.

Trying this (I replaced thisModule by core.sys.windows.winuser 
everywhere) I get the following errors for the line with the "writeln":

Error: unexpected ( in declarator
Error: basic type expected, not ": "
Error: found ": " when expecting )
Error: no identifier for declarator writeln(memberName, _error_)
Error: semicolon expected following function declaration
Error: declaration expected, not ,

Wondering why the "writeln" bombs out here...
