I used to do some scripting in mIRC a while back, quit for a long while, and have recently started to script in mIRC again. I am looking at other people's scripts to get ideas on how to do things, and have always wondered one thing. I have seen a lot of scripts, and some do command while others do .command. I have never asked before and never thought to ask, but what is the difference? Examples below:

Code:
somealias {
  var %somevar sometext

  echo %somevar
}


Code:
somealias {
  .var %somevar sometext

  .echo %somevar
}
