I had idea - building own interface to read lots of parameters to scenes from
external file with simple syntax
the easiest way should be prepare special patch but I wanted write parser as
macro and try parsing of parsing :-)
I imagined that first char of my definition file could be " and last one too -
this means that this definition file would be one long string
I thought that such construction should do what I want :

#macro parse_model(file_name)
  #local Input=#include file_name
  // parsing stuff
#end
parse_model("input.txt")

but for my input file fastly I recived message : String too long

than I found such information in help : <<String literals begin with a double
quote mark '"' which is followed by up to 256 printable ASCII characters and are
terminated by another double quote mark.>>
hmm, I can't but ... perhaps with #read ?
I looked in manual something about max length of string variables (not string
literals) - and I didn't found anything - than I checked this script :

#declare A=" "
#declare A=concat(A,A) // 2
#declare A=concat(A,A) // 4
#declare A=concat(A,A) // 8
#declare A=concat(A,A) // 16
#declare A=concat(A,A) // 32
#declare A=concat(A,A) // 64
#declare A=concat(A,A) // 128
#declare A=concat(A,A) // 256
#declare A=concat(A,A) // 512
#declare A=concat(A,A) // 1024

it was parsed and run fine
than I changed my parsing macro to this:

#macro parse_model(file_name)
  #local Input=""
  #fopen InputFile file_name read
  #read (InputFile,Input)
  #fclose InputFile
  // parsing stuff
#end
parse_model("input.txt")

but again I achived message : String too long

than I again typed test but this time with showing result at end

#declare A=" "
#declare A=concat(A,A) // 2
...
#declare A=concat(A,A) // 1024
#warning concat(A,";\n")

and this caused the most strange thing
povray exited
no, not crashed, just disapeared from tasks and from screen
it wasn't even normal exit becouse after next start he forgot names of opened
files
I've tested this with MegaPOV 0.7 and with good _old_ POV-Ray 3.1g on Windows NT
4
and both exited

two things:
1. can anybody confirm this bug ?
2. can anybody propose another simple method for build reading from external
text file with specified structure ?

thanks for long reading

  Could you post a short code that causes the bug so that we could just
test it right away? It would be the easiest way.

  The behaviour you are describing sounds like a memory leak or similar
(povray writes to unallocated memory).

: 2. can anybody propose another simple method for build reading from external
: text file with specified structure ?

  Like for example the PCM file format?

The bug is part of "String literals can only be 125 characters long" in
povray.bugreports posted Thu, 3 Jun 1999 01:56:56 +0200, Message-ID:
<3755c4f2.0@news.povray.org> .   The bug is fixed in POV-Ray 3.5 (not
release yet).

but ... it is sended in my post :-)

#declare A=" "
#declare A=concat(A,A) // 2
#declare A=concat(A,A) // 4
#declare A=concat(A,A) // 8

it is fixed but for what ?
to be 255 characters long or to be unlimited ?
I hope it's not discussion about 3.5 :-)
