Python | sys.argv | len(sys.argv) | first argument |
S-Lang | __argv | __argc | first argument |
Fortran | DO i = 1,argc CALL GET_COMMAND_ARGUMENT (i,argv(i)) ENDDO | argc = COMMAND_ARGUMENT_COUNT | CALL GET_COMMAND_ARGUMENT (0,progname) |

OCaml | Sys.argv.(n) | Array.length Sys.argv | first argument |
F# | args. | args.Length | Assembly.GetEntryAssembly.Location |
Standard ML | List.nth (CommandLine.arguments , n) | length (CommandLine.arguments ) | CommandLine.name |
Haskell (GHC) | do { args <- System.getArgs; return args !! n } | do { args <- System.getArgs; return length args } | System.getProgName |
- ^a The command-line arguments in Visual Basic are not separated. A split function Split(string) is required for separating them.
