I can't seem to #read using close to the example in 
the Documentation. The example below errors that var2 
is an undeclared identifier. 

I've tried with and without a trailing comma, after 
xf5 and before the closing quote 

Am using version 3.6.1.c.id8.win32 on WinXP. 
Any suggestions much appreciated. 

// if first time through, then write file 
#if (clock = 0)
 #declare xf1 = 4.30 ;
 #declare xf2 = 5.30 ;
 #declare xf3 = 6.30 ;
 #declare xf4 = 7.30 ;
 #declare xf5 = 8.30 ;
 #declare xf6 = 9.30 ;
#fopen MyFile "shapesA.txt" write
#write(MyFile,"\"ShapesA\",",xf1,",",xf2,",",xf3,",",xf4,",",xf5"\n")
#fclose Myfile
#end

#declare var1 = 1.1 ;

// read from file 
#fopen Infile "shapesA.txt" read
#read (Infile, Txt1, var1, var2, var3, var4, var5)
#fclose Infile       
#debug concat("\n\nClock = ",str(clock,1,2)," \n")
#debug concat("File read -> ", str(var2,1,1), " \n")

I think there is a " missing after ShapesA\" in the line above. It should 
probably be:

#write(MyFile,"\"ShapesA\"",",xf1,",",xf2,",",xf3,",",xf4,",",xf5"\n")

I don't know if this will fix the problem though.

No, as written does make sense. And the file #write works OK 
to disk. After the #write section a file appears containing; 
"ShapesA",4.3,5.3,6.3,7.3,8.3     as expected. 

I remain baffled that the #read doesn't load the string and floats.

The reason is that the MyFile (I mean your file) is still open.
   Just use #fclose MyFile
instead of #fclose Myfile

No, I don't understand.  See below that Myfile 
is opened and closed for the #write.  And that 
Infile is opened and closed for the #read. 

// if first time through, then write file 
#if (clock = 0)
 #declare xf1 = 4.30 ;
 #declare xf2 = 5.30 ;
 #declare xf3 = 6.30 ;
 #declare xf4 = 7.30 ;
 #declare xf5 = 8.30 ;
 #declare xf6 = 9.30 ;
#fopen MyFile "shapesA.txt" write
#write(MyFile,"\"ShapesA\",",xf1,",",xf2,",",xf3,",",xf4,",",xf5"\n")
#fclose Myfile
#end

#declare var1 = 1.1 ;

// read from file 
#fopen Infile "shapesA.txt" read
#read (Infile, Txt1, var1, var2, var3, var4, var5)
#fclose Infile       
#debug concat("\n\nClock = ",str(clock,1,2)," \n")
#debug concat("File read -> ", str(var2,1,1), " \n")

	Pov is case-sensitive, therefore MyFile is different from Myfile...

You use "MyFile" to open,
but "Myfile" to close,
POV-Ray identifiers are case sensitive,
and hence file "MyFile" is still open.
Again, if we replace "#fclose Myfile"
with "#fclose MyFile" it works as it should.

Well put, Jerome.  I thought either I or Bart was 
crazy for a bit there. Now I can see that I need 
better glasses.   Many thanks.
