Does anyone have experience using system command and command-line
arguments using fortran with g77 on a Sun workstation?  Any help
will be appreciated.

Using DOS and MS Fortran 5.1 the code was:

1) system commands

      INTERFACE TO INTEGER*2 FUNCTION SYSTEM [C]
     &   (STRING[REFERENCE])
      CHARACTER*1 STRING
      END

      PROGRAM MAIN
      INTEGER*2 I,SYSTEM

      I=SYSTEM("system_command")

      END

   This was useful for spawning an EXE or listing a directory.

2) command line args

      PROGRAM MAIN
      CHARACTER*80 PATHX,INPUT
      INTEGER*2 IP,IPX

      CALL GETARG(0,PATHX,IPX)  ! EXE path
      CALL GETARG(1,INPUT,IP)   ! 1st command-line input

      END

Thanks

arguments in different system in the beginning of this month. I don't
know if it yet is added to the FAQ.

Hope this give some help,

From yet-unreleased documentation:

 - Intrinsic subroutine: getarg N S
          integer N
          character*(*) S
     Sets S to the N-th command-line argument (or to all blanks if
     there are fewer than N command-line arguments); `call getarg(0,S)'
     sets S to the name of the program (on systems that support this
     feature).  See `iargc' below.

 - Intrinsic subroutine: system CMD RET
          character CMD
          integer RET
     Passes CMD to a shell (see `system(3').  If argument RET is
     present, it contains the value returned by `system(3)'.
