Commas are used between multiple parameters of a Lasso tag. Each keyword, value, keyword/value, or name/value pair is specified followed by a comma and the next parameter.

[TagName: Tag Parameter, Tag Parameter]

<?LassoScript
  TagName: Tag Parameter, Tag Parameter;
?>

In previous versions of Lasso either a colon or a comma could be used after a tag name in all tags. Since Lasso 6 only a colon is allowed. Use of a comma is now a syntax error.
