Pros:

• efficient and easy to use
• Original =)

Cons:

• Setting unnecessary variables
• Doesn\'t check if the the dialog is in use when opening.

Use local variables: var %ajs 1 and var %ajd 1. You can also create an alias that opens the dialog: alias aj.open { if (!$dialog(aj)) dialog -md aj aj } <- That\'s just an example. Sometimes it\'s easier to type the alias. On average, this is a really nice snippet. Good job.
