VBScript

For Each arg In WScript.Arguments
    WScript.Echo arg
Next

For i = 0 To WScript.Arguments.Count - 1
    WScript.Echo WScript.Arguments(i)
Next

JScript

var arg = new Enumerator(WScript.Arguments);
for (;!arg.atEnd(); arg.moveNext())
    WScript.Echo(arg.item());

for (var i=0;i<WScript.Arguments.length;i++)
    WScript.Echo(WScript.Arguments(i)); // 配列ではないので Arguments[i] ではない

for (arg in WScript.Arguments)
    WScript.Echo(arg); //何も表示されない

Perl

foreach $arg (@ARGV)

Python

Ruby

ARGV.each do |arg|

Scala
