Don't forget that POV will not place anything in between it's output unless you
tell it so. eg the numbers 12, 18, and 5 will appear as 12185 in your output
unless you do something like this...

#write (SeedValue1," ",SeedValue2," ")

etc. which will put spaces between them. You get the picture. Stick with the
pov manual, and constantly look it up. It really is handy. Within weeks, it'll
become your most used help file, I guarantee.
