SYNOPSIS

use M_f2kcli, only: command_argument_count use M_f2kcli, only: get_command use M_f2kcli, only: get_command_argument

DESCRIPTION

The M_f2kcli(3f) module contains procedures useful for reading command line arguments from Fortran programs in Fortran 90 programming environments that do not support the new Fortran 2003 standardized procedures.

An extensive set of such routines is available on-line from Winteractor. The M_F2KCLI(3f) module found here is based on a single routine from this collection.

M_F2KCLI is an implementation of the Fortran command line interface as defined in the Fortran F2003 standard:

    COMMAND_ARGUMENT_COUNT : Returns the number of command arguments.
    GET_COMMAND_ARGUMENT   : Returns a command argument.
    GET_COMMAND            : Returns the entire command by which
                             the program was invoked.

F2KCLI(2f) is intended to provide the definitive solution to the long standing lack of standardised command line access in Fortran, until F2003 compilers become generally available.

Sample program

   program demo_M_f2kcli
   use M_f2kcli, only : command_argument_count
   use M_f2kcli, only : get_command
   use M_f2kcli, only : get_command_argument
   implicit none
   character(len=256) :: line
   character(len=256) :: exe
   character(len=40)  :: cmd
   integer            :: narg,iarg
      narg = command_argument_count()
      write(unit=*,fmt=*) "Arg count=", narg
      call get_command(line)
      write(unit=*,fmt=*) "Line=",trim(line)
      call get_command_argument(0,exe)
      write(unit=*,fmt=*) "Program=",trim(exe)
      do iarg = 1,narg
         call get_command_argument(iarg,cmd)
         WRITE(unit=*,fmt=*) "Arg ",IARG,"=",CMD
      enddo
      stop
   end program demo_M_f2kcli
