Umm. Then I am a tad confused... Do you mean executing that program from 
inside POV? Unless this is what you mean, then I haven't a clue what you 
are talking about here. I am talking about limited the total size of the 
file you load in POV-Ray by chopping up the original into smaller bits, 
so when you do use them, you are loading much smaller ones.

As for it being the same operation. Some programs are memory hogs, have 
glitches when dealing with truly hug files, etc. And not all of us can 
afford to buy one that doesn't to replace whatever we are already using. 
The fewer extra programs you have to fiddle with to get something done 
the better imo.

    call functional_code()
