NAME
getarg, iargc - command arguments to Fortran
SYNOPSIS
subroutine getarg(argno, string)
integer argno
character *(*) string
iargc()
DESCRIPTION
These procedures permit Fortran programs to access the command argu‐
ments. The integer function iargc returns the number of command argu‐
ments. The subroutine getarg stores the argnoth command argument in
its second argument. The string is truncated or padded with blanks, in
accord with the rules of Fortran character assignment.
The command
a.out arg1 argument2
provides 2 as the value of iargc. If s is declared character*4, then
call getarg(2, s)
will put `arg1' in s.
