go to post Vitaliy Serdtsev · May 26, 2017 Anything with this flag can change or be removed with no warning. There are a few comments: Let's say that the developers changed something in new versions of the DBMS. Is this a problem? It is enough to check Caché Recent Upgrade Checklists, where usually there is a ready list of changes that may affect existing user code, for example. Note that this can apply to absolutely any member of a class, and not even marked as [Internal]. Suffice it to recall the recent story with JSON support. For a class does not exist flag [Internal], the warning is only on the level of comments. As for the other members of the class, according to the documentation this flag is for other purposes, namely: Internal class members are not displayed in the class documentation. This keyword is useful if you want users to see a class but not see all its members. proof In any case, the final choice for developer.
go to post Vitaliy Serdtsev · May 25, 2017 Does this example need to handle this? Correct, of course, to close the device: #include %systemInclude #dim cDev As %String = $IO ; see "dir /?" and RunCommandViaZF() d ##class(%Net.Remote.Utility).RunCommandViaCPIPE(...,.dev,.con) /* ... */ c:($get(dev)'="") dev:"I" u cDevAlso, do you not worry that its an internal class? No, since for me internal ≠ deprecated. However, given the openness of the source code, you can make own similar method, thereby to protect yourself from possible issues in the future.
