  [POVWIN RC1] Is file I/O working properly? (Message 1 to 4 of 4)

#fopen File "skylight.ppm" write
#write (File, concat("P3\r", str(10,0,0), " ", str(10,0,0), "\r255\r"))
#declare Y = 0; #while (Y < 10)
  #declare X = 0; #while (X < 10)
    #write (File, concat(str(X,0,0), " ", str(X,0,0), " ", str(Y,0,0), " "))
  #declare X = X + 1; #end
  #write (File, "\r")
#declare Y = Y + 1; #end
#fclose File

Changing all \r to \n produces a 36 byte-length file; the output from the
first #write and then ten returns.

Can anyone verify this problem?

System details:
AMD Athlon XP 2600+ (1.91GHz)
1GB DDR memory
Windows XP Pro

PoV-Ray version:
3.6.release-candidate.1.icl8.win32

Opps - there was originally a paragraph at the top of the previous post:

'I set the script I/O restrictions to no restrictions, permit read/write in
the current directory, even explicitly unset the restrictions in the
pvengine.ini but the following code, which worked OK with the last beta,
creates a zero byte-length file:'

I seem to have lost it in the preview process without noticing. 8-/

yes.

I introduced some changes to the most recent build to correct the problem
where other text files written by POV (e.g. INI files) would be LF-only,
or in some cases a mix of CR/LF and LF. At a guess I'd say this has broken
the above code. I'll find and fix this.

Thanks Chris. I was hoping I hadn't missed something obvious ...
