czardas Posted December 21, 2012 Share Posted December 21, 2012 That looks so strange and weird. I also think it's odd to have Dim depreciated while not also depreciating ReDim.

czardas Posted December 21, 2012 Share Posted December 21, 2012 (edited) Dim and ReDim are two totally different things.Even so, etimology suggests at least a very strong link.

I think there is a name for that syntax after some old school programmer, but for the life of me can't remember.I used to be really bad at doing that, and still revert to bad syntax when throwing out examples.I don't know what is a normal prefix for static, I never saw that keyword before perusing this thread.At first I didn't even get why people put those prefixes in, then once I got it I thought it would slow me down.

DicatoroftheUSA Posted December 21, 2012 Share Posted December 21, 2012 How to make a variable visible to all functions?Passing the value through arguments. Though in some cases such as event or callback functions, there may not be an alternative.But I still prefer using local/passed argument variables, because cause/effect is easier to trace in my opinion.

czardas Posted December 22, 2012 Share Posted December 22, 2012 (edited) How to make a variable visible to all functions?Yes that can be tricky without using globals. To most functions, I generally pass an array of values stored locally within a main function, or read values when I need them: for example from an ini file. It's not always possible to avoid using global declaration, but I believe it is good practice to avoid them.

AZJIO Posted December 22, 2012 Share Posted December 22, 2012 for example from an ini file.If you suggested to use the register, I would reflect.INI-file is not professional.

czardas Posted December 22, 2012 Share Posted December 22, 2012 (edited) The ini file was just an example of reading a value instead of having it declared globally. I generally do something like this: Instead of this: Global $gArg1 = True, $gArg2 = False Func _main() _1of2($gArg1) _2of2($gArg2) EndFunc Func _1of2($vParam) ; some algorithm EndFunc Func _2of2($vParam) ; some algorithm EndFunc Try to do something like this: Func _main() Local $aArgs[2] = [True, False] _1of2($aArgs[0]) _2of2($aArgs[1]) EndFunc Func _1of2($vParam) ; some algorithm EndFunc Func _2of2($vParam) ; some algorithm EndFunc This is the simplest example I can think of. Instead of using global, try to use local variables. Edited December 22, 2012 by czardas operator64 ArrayWorkshop Link to comment Share on other sites More sharing options...

czardas Posted December 22, 2012 Share Posted December 22, 2012 (edited) The reason is that you accidentally used a reserved name?Yes, I think this is the main reason, especially if someone tries to combine different UDFs which use conflicting global constants. That can get really quite awkward. The fewer globals, the better. Edited December 22, 2012 by czardas operator64 ArrayWorkshop Link to comment Share on other sites More sharing options...
TheSaint Posted December 22, 2012 Share Posted December 22, 2012 (edited) There are many uses of Global variables in most of the included UDFs, definitely not a no-no to the devs. Every XXconstants.au3 file is nothing but global variables. It all depends on what you need the variable for that decides its scope.Very true, perhaps I should have said, that if you have to use a Global in a UDF or Include, that you damn well better make sure it is uniquely named and extremely unlikely to be used in a script that could use them.I've never created either, but I have very carefully modified a few, and encountered the perils of Globals in them.Is there a set standard for this, like using a certain format, combo of characters, underscore etc?EDITI never make changes to the Includes that come with the AutoIt install, certainly never permanently.It's mostly ones other people have whipped up. If I have to alter an AutoIt original, it is never to one in the Include folder, but to a copy in my script folder, for a one off scenario.
