I have had several of these typos in the past and they never caused problems. In the example below pParam is argument 1. The comma is ignored.
command test, pParam answer pParam end test The parser is much better in v8 but could still be tightened up a bit. An example is extraneous closing parens in "if" or "repeat" expression constructs are no longer ignored. They didn't cause parsing errors prior to v8. My comma in the above example is minor compared to the other LC goals at hand for the team.

Because most languages require commas separating arguments, and because calling a handler explicitly requires them, it never occurred to me that the definition would allow them to be optional. Ideally the same rules would apply on both sides. I can kinda understand why they don't here, but if we had comma-free arguments we could add syntactic sugar to make things more English-like, e.g.: DoSomething with a and b Two questions: How many of you have never before known that commas are optional between definition arguments? For those who've known about this, were you confused to discover that this only works for definitions but not calls? -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ____________________________________________________________________ ambassa...@fourthworld.com http://www.FourthWorld.com _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
