[Squirrel-sql-users] Prompt for dynamic value in query

[<ep...@we...>]

Ok, I know I've done this before in SquirrelSQL, but I've trying to 
relearn the syntax (plugin?) for running a query that prompts me for a 
dynamic value.  Been searching the docs/web to no avail.

A quick 'n dirty example would be awesome.

Thanks,
Eric P.
