Did you post the exact code? After adding the opening bracket after the
prism, and removing the unused #end directive, the code rendered fine under
POV 3.1g and MegaPOV. The error message indicates you are running out of
data (i.e. there are less points than the first number in the file
indicates). POV-Ray undefines the file handle when it reaches the end of
the file.
