I think I wasn't even much aware that an online dictionary existed. I was about to post that I don't see why updating the web version when there's a new release was a problem, but then I looked at the page source of the web dictionary. While the local dictionary that opens in a browser is clean easy-to-read-and-understand html, the web site is a mess. It's 90% css and the other half is ad-tracking analytics. Easy to see why it's not maintained.

Re: return "error" code from standalone compile
I use the online dictionaries (LC's and Brian Milby's) when I'm reading the list or the forums, or any other time I'm curious about something, and I'm on my tablet, phone, or Chromebook. None of the online resources are perfect, though Brian's is the most up to date. Often I want to check syntax or copy an example when composing an answer. I wish LC would always show complete info from the latest release. Sometimes I just want to know something. Like, say, error codes on quit. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com Mark Wieder wrote: Why are you looking at the web version of the documentation instead of the local one? ___ 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

Thanks, but I'm pretty familiar with the docs options in our community. I even know our community manager pretty well. ;) The bigger problem with these sorts of issues is how the public web site becomes so different from the ones we have installed. I can hunt down good docs. The general public won't know to do that. Moreover, limiting the public-facing Dict to Community-only obviates the upsell opportunity. But beyond the missed opportunity, from time to time it's also just the wrong content. -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://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

I considered it, but then it occurred to me that anything in the list would become public knowledge and thereby no longer qualify for inclusion in such a list. ;) More seriously, I used to maintain a list in a document titled "mode 16", but I can't find it right now so I can't recall how you stumbled across "mode 16" or the other notes there.

RE: return "error" code from standalone compile
I use AUTOHOTKEY... as a fast, dirty way to "get stuff done" when I'm either too lazy or too rushed to do a "quality" job with Livecode. It has a command called "Run" & "Runwait" ... which returns the calling program's (Livecode executable, in this case) return code into a predefined variable called "ErrorLevel" (how original!). So a line in a AUTOHOTKEY script for this would look like: cmd = c:\livecode\SomeLiveCode.exe RunWait, %cmd%,,UseErrorLevel exitcode := ErrorLevel if (exitcode > 1) Autohotkey takes some getting used to but I think it's a handy addition to development projects.. since AHK scripts can be compiled into executables, themselves.

Re: return "error" code from standalone compile
Since Livecode is written in C++ here is some info about using return in C. Every C program has a function named main. At the end of the function the programmer usually writes a return 0; That tells the c program the code has completed and is exiting with a 0 value which confirms it has successfully executed the code and is quitting. At any point above that line the programmer can write a return call but they will usually use a 1 on another value.

Re: return "error" code from standalone compile
Every application can have its own exit codes, but 0 should always be used for success and 1 for error. Although there are exceptions. The Dos Find command for example returns 1 when the search was successfull but nothing was found. You could use exit codes for example in batch files. The batch file runs a program and according to the exit code of that program the batch file executes the next command or application or what ever. The OS is not interested in the exit codes. ;) But maybe the batch file or program that executed the other app. I am using this feature for example in some of my LC app where i execute a 3rd party command line tool using shell(). 'The result' then contains the exit code. Important: If the exit code is 0 then 'the result' is empty.
