Does anyone know away around this or do I have to abandon my

I suppose you could pass false instead of empty and check for that.
I don't think this would work either. Wouldn't :
get GetXY(theDocRef,false,myYValue)
by the same as:
put false into myXValue
get GetXY(theDocRef, myXValue,myYValue)
What I was thinking is that you can pass false for theXValue/
theYValue if you wanted the function to act as if those parameters
weren't passed. Passing empty would mean you passed in an empty
value. With Rev you have to pass a variable as the parameter when
passing by reference. Looking at your first post it doesn't even
look like the get code
get PDFGetXY(theDocumentRef,empty, empty)
would execute without an error. Does it work on your end?
Ahh, ok, I didn't get that far since it didn't work on the case where
I passed two variables into it. I've abandoned the idea now. I've
been coding in C this afternoon and I guessed some of that rubbed off
when I switched back to RunRev. In C you'd pass NULL to the function
or &myXValue. In function you'd check the value for <> NULL and if so
store the value. This is a standard way of doing things in C and I
thought I could use a similar technique in RunRev, it turns out I
can't. Doesn't really matter,
Thanks a lot for taking the time to look at this
All the Best
Dave
