I can't find those functions; are you sure they are part of the Rev 
externals SDK?  I can't seem to find them in the headers or in the 
documentation stack.  The documentation stack seems to indicate that 
GetVariableEx and SetVariableEx should be used for binary data, which 
is what I am using, but GetVariableEx does not seem to work.
