How to Pass Command Line Parameters in batch file |

I needed to pass id and password to a cmd (or bat) file at the time of running rather than hardcoding them into the file.
Here's how I do it.

Here's what the command line looks like:

Good question. If reversing the "ON" bits means reversing only the bits that are "ON", then you will always get 0, no matter what the input is. If it means reversing *all* the bits, i.e. changing all 1s to 0s and all 0s to 1s, which is how I initially read it, then that... |

Javascript doesn't really have namespace or packages like other languages. Instead it has closures. If you have an application that consists of multiple functions, variables and objects, then you should put them inside a single global object. This will have the same effect as a namespace.

Downside? It's fairly limited - you trigger a "GET" request and get back some script that's executed.

You're at the mercy of the various browser author opinions of "... |
