I don't see where you include Tank.INC from Tank.POV.
(BTW, it is usually a good idea to place the problem description
/before/ any snippets of source code, because it makes it immediately
obvious for the reader what your problem actually is, and may give
important clues what to keep their eyes peeled for when browsing through
the code.)

THAT has gotta be the problem; i had a different program set that worked, and
still works despite incorrect library reference in the \renderer\povray.ini (or
whatever the name is, i forget because i almost never have to hunt for it).
Thanks.
Will fix it (on different drive not accessible now).

Then i made some changes and it is worse than before.
Declared variables now do not pass between .ini and .inc; worse a declared

Debug file "true" (no other name possible) shows that PN=0 !!
Furthermore POVray barfs on undefined variable Ulong in Tank.inc .

If you want to output PN, then why do you output B ?! ;-)

By defining it /before/ you include the file??
But from the code I guess you'll also want more than one "U-bar" in the
long run anyway, with different lengths - your current code cannot
accomplish that anyway. You should have a look at POV-Ray's macro
mechanism for that. Essentially, macros are the only way in POV-Ray to
"pre-define" anything without specifying all the parameters beforehand.

I finally discovered that.
I thought i could be "cute" and include the .inc file right away and thus make
it global.

maybe some thing in the include file is miss-matched ... dunno if the
parser looks at the include as a seperate entity or considers it as part
of the entire scene file when resolving conditional blocks ... /think/
it's the former

No, the parser doesn't systematically check whether the #if and other
blocks of an #include file are fully matched.
An exception is when the parser encounters an #end for a loop it is
currently processing; in that case the #while or #for must reside in the
same file as the terminating #end.

Thanks loads for the patience; learning as i go.
The business about "subroutines" is something a bit different than in other
languages; quite different than even the 2 ways available in BASIC.
The above info on #if..#end became pertinent WRT POVray "subroutines".
Let's see if i can say this correctly.
Start in .POV and an object is named.
The program "looks" to see if it is / has been defined in .POV and if not,
scans the .INC files.
If found in <workingname>.INC then the contents get copied (acts as if one had
a very long file) and then run.
In my case, the .INC file had an un-matched #if..#end so when the program
continued (effectively "went back" to the .POV file) it did not find a matching
#end and so complained about finding an EOF.
Now, i think that the program actually does all of the work as it scans thru
all of the pertinent files, and saves the results in some ?hidden? temp area
until done (error or not).
Then, if error, the appropriate line(s) and file name are used for the message
file - and all results are then scratched / released / erased.
If no error, one gets all if the neat picture(s), etc.
