1. I can't imagine what defined() has to do with any of this.

2. POV's #read command doesn't see the file as a series of lines, it
sees it as a series of fields separated by commas. If you don't have
commas between each of your fields it will miss them. 

3. That's no good. It doesn't have any commas.

4. Only if the data file contains the fields in vector format, like this
        <-0.5,0,-0.5>,
        <0,0,0>,
        <0.2,0,0.2>,
        <1,1,1>
Note that the commas after each vector are required. The line breaks are
not required, sot you can write it like this if you prefer.
        <-0.5,0,-0.5>,<0,0,0>,<0.2,0,0.2>,<1,1,1>

POV doesn't know in advance what sort of field it is expected to try to
read. If is sees a vector it reads a vector. If it sees a number it
reads a number. If it sees a quoted string it reads a string. It doesn't
matter if the variable already contains a different type of object.

5. You can give the file any extension you like, but it has to contain
ASCII text in the specified format.

6. You're welcome
