[Swift-user] passing a file as an argument

[J A]

Hi:

I tried that but got an error ...


*the command is:*

$ swift  CreateFiles.swift  -fname=list.txt


*My code looks like this:*


type file{};
type messagefile {};
//file list<"list.txt">;     // if I uncomment this line and comment the
next line, my code will work fine but I want the file name
                                 // to be dynamic
file list<@arg("fname")>;
..
...
...


*The error I got was:*


$ swift CreateFiles.swift -fname=list.txt
Could not compile SwiftScript source: line 7:11: unexpected token: @



Thanks for your help.

Jamal
