[Pw_forum] plotband.x could not get filename

[Yan]

Dear Paolo,

Thank you for your reply.  I tests iargc with test.f90, it works and returns 
correct number of arguments.

!--------test.f90---------
PROGRAM test
   IMPLICIT NONE
   INTEGER :: iargc, nargs

   nargs = iargc()
   write(*,*)  nargs

   RETURN
END PROGRAM
!--------end-------------

bash-3.2$ gfortran test.f90 -o test
bash-3.2$ ./test
           0
bash-3.2$ ./test 1 1
           2

Could you give me some more hint about how to locate and fix this problem?
Thank you.

Yan
