I'm trying to import an Inventor file created with the "revo" demo tool, to my
Performer 1.2 application using the LoadIv() routine. The routine doesn't seem
to recognize the tokens in the file. Why?

(By the way, "revo" outputs files in Inventor 2.0 format. I've converted the
files into Inventor 1.0 format using the "iv2toiv1")

The file looks as follows:

#Inventor V1.0 ascii

Separator {
    ShapeHints {
        hints (ORDERED | CONVEX)
    }
    Coordinate3 {
        point [ 0.5 -0.2 0,
