I believe the error message is OK, but I leave it to our experts to
check the standard.

I get with gfortran 4.3/4.4, NAG f95  5.1, g95, pathscale 3.1, pgf95 7.1
the same output (modulo a few spaces):

 0 0 0
 line =  255,255,255
 Error

while gfortran 4.1/4.2, ifort 11, sunf95 and openf95 print:

 0 0 0
 line =  255,255,255
 255 255 255   <<<<<<<<<< Note the extra line.
 Error


Without 'err=1' one gets the run-time error messages:

gfortran 4.3/4.4: Fortran runtime error: Bad value during integer read
NAG f95: Invalid character in integer input field
g95: Fortran runtime error: Bad value during integer read
pgi: PGFIO-F-217/formatted read/internal file/attempt to read past end
of file.
pathf95:   A READ operation tried to read past the end-of-file.


I think it is OK to give an error when reading the string:

' 255,255,255 '
 1234567890123

using the format '(3I12)'. Using I12 one grabs " 255,255,255" which I
would regard as strange integer string. (What is the meaning of "," in
an integer?)

However, I might miss something and the "," is regarded as separator
even in this case and it overrules the "I12". Jerry, what do you think?
