Dear PWSCF users,

I met such a problem when drawing phonon dispersion:
bash-3.2$ /home/pem/espresso4/espresso.4.0/bin/plotband.x  myFileName

: too many arguments   -1                                                        
At line 42 of file plotband.f90 (unit = 1, file = '')   
for anything I typed after plotband.x , it gives the same error info. I find 
plotband.f90 and modified line 42 as bellow:

 call get_file ( filename )
-   open(unit=1,file='filename',form='formatted')
+ open(unit=1,file='myFileName',form='formatted')

after recompilation, now /plotband.x works with this file. I think there is 
something wrong with the subroutine 'get_file'(from flib/inpfile.f90), but I 
don't know exactly where. 

My QE version is 4.0. I've tried the inpfile.f90 from 4.1cvs, and it gives the 
same error.

Every describable physical law will turn out to be an error some day.
