I had an Idea for faking random access files for POV.
If you put Data in strings and place them to a file in a form POV can Read.
Then when you a particular piece :
  open the file and read until you got it then close the file.
And then your ready for another Read

I was wondering if anyone used something like this. And how efficient it was.

I did some like this for animation robots but the input file was coded as to how
the file was read.

Thanks!

yes and no.  I did write a file handling macro[*], the data can be (any) scalar
types, as "CSV".  or you could store (lists of) data within strings, and use eg
the 'strSplit()' macro (see link) to parse.
