Next scene gives an error "Expected 'undeclared identifier', empty array 
found instead" when I try to render it. Aren't A[0] and A[1] undeclared 
identifiers and shouldn't Pov-Ray turn them "into global identifiers of 
the type determined by the data which is read". If I uncomment the 
commented line, it works. What am I missing here and how should I 
correct the code to make it work?

PS. Don't forget to delete the test.dat this scene creates...

-----------------------

#declare A = array[2];

//#declare A[0]=0;

#fopen P_File "test.dat" write
     #write (P_File, 1,",",2)
#fclose P_File

#fopen P_File "test.dat" read
     #read (P_File, A[0],A[1])
#fclose P_File

But A[0] & A[1] are declared...

And since it is uninitialized, the error is correct.
Try
#fopen P_File "test.dat" read
    #read (P_File, A0,A1)
    #declare A[0] = A0;
     #declare A[1] = A1;
#fclose P_File
