As I understand, this is LC version of the “spread operator”. It allows you to spread the elements of an array as the arguments to a handler. The code: put “an...@example.com <mailto:an...@example.com>” into tDataA[1] put “Andre Garzia” into tDataA[2] sendEmail …tDataA Is syntactically equivalent to: put “an...@example.com <mailto:an...@example.com>” into tDataA[1] put “Andre Garzia” into tDataA[2] sendEmail tDataA[1], tDataA[2] Which means that you can code the “sendEmail” command to have two string arguments instead of an array, as shown below: command sendEmail pEmail, pFullName // send your email end sendEmail The spread operator will pass every array element as an argument to the handler. It would be beneficial if this feature would also come paired a “rest operator” that collected extra arguments in an array, so that we could declare the “sendEmail” handler as command sendEmail pEmail, pFullName, …pMoreArgumentsA // stuff end sendEmail This way, if the call uses an array that contains more than two elements, the remaining parameters are collected in the final “pMoreArgumentsA” array. That if what I would like to have, LC didn’t say anything about this but it is very common in other languages to implement both operators at the same time. In the case of LiveCode there is an alternative though. We can use “paramCount” and “param()” to grab the extra parameters, but that requires us coding it while something like a “rest operator” do that for us automatically. _______________________________________________ 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
