According to the docs (6.2.3.4)
"hello", 1,2
ought to be a valid input line from a file (string, float, float)
However, this generates an error, which is fixed by:
"hello", 1,2,
(requires final comma)

works according to doc for me
do you read in loop ? perhaps there is one extra reading according to your while
condition
check this source
#fopen wfile "nothing.txt" write
#write( wfile , chr(34) , "hello" , chr(34) , ",1,2" )
#undef wfile
#fopen wfile "nothing.txt" read
#read( wfile , S, F1,F2 )
#warning S
#warning str(F1,0,0)
#warning str(F2,0,0)
> 2.5.beta9.icl.win32
please upgrade to 3.5 ;-)

Hmm, that's okay, but this version fails without a comma (e.g. ",1,2,\n")
#fopen wfile "nothing.txt" write
#write( wfile , chr(34) , "hello" , chr(34) , ",1,2\n" ) /* bad */
/* #write( wfile , chr(34) , "hello" , chr(34) , ",1,2,\n" )*/ /* good */
#write( wfile , chr(34) , "hello" , chr(34) , ",1,2" )
#undef wfile
#fopen wfile "nothing.txt" read
#read( wfile , S, F1,F2 )
#warning S
#warning str(F1,0,0)
#warning str(F2,0,0)
#read( wfile , S, F1,F2 )
#warning S
#warning str(F1,0,0)
#warning str(F2,0,0)

This is because a line-feed is not counted as an item separator, only commas are.
Bye for now,

But why you need separator after third component when you end reading at this
third component ? "\n" is only white space.

Hmm, yes I realise that - all I can say is that I have never come across a
scripting lang. that behaves in this way. Could someone confirm that this is the
way that POV is meant to behave. If it is, then I would suggest some
clarification in the docs, since this will confuse Perl users for a start....

It would appear that in some ways POV is behaving as though it is globbing the
whole input file in one operation, and yet it isn't. Could someone confirm that
this is the intended behaviour?

Hmm, no further comment. Anyone want to confirm whether this is a bug or not?

Well, it seems to be doing exactly as it should, to me.
Outputting lines 3 & 4 of your test code 'nothing.txt' is
"hello",1,2,
"hello",1,2
which is read correctly.
With lines 2 & 4 you get
"hello",1,2
"hello",1,2
which causes a parsing error when it tries to read the second "hello"
because it is not preceded by a comma.
So IMHO this works as given in the documentation (ss6.2.3.3).
Bye for now,
Mike Andrews.

I have rechecked all scripts from this thread and all works for me as expected,
but I remember there was something wrong imo.
Btw: there is general rule that commas are optional but it probably applies only
to script.
