Radiance Posted December 15, 2015 Share Posted December 15, 2015 (edited) I didn't find anything so here's a general coding question.I'm calling a function that has 1 parameter. Depending on the parameter the function needs to declare different varables.Func _DoStuff($iParm) Switch $iParm Case 1 Local $sVar1 = "w", $sVar2 = "x" ; do stuff Return Case 2 Local $sVar3 = "y", $sVar4 = "z" ; do stuff Return EndSwitch EndFuncDoes declaring like this make sense?How will this code affect my memory? Will all four variables be declared once the function is called or will only two of them be declared once the condition matches?

water Posted December 15, 2015 Share Posted December 15, 2015 The variables will be defined when AutoIt processes the Local statement. You could check after EndSwitch.If IsDeclared("sVar1") Then ConsoleWrite("$sVar1 is declared") If IsDeclared("sVar3") Then ConsoleWrite("$sVar3 is declared") Radiance 1 My UDFs and Tutorials: Spoiler UDFs:Active Directory (NEW 2022-02-19 - Version 1.6.1.0) - Download - General Help & Support - Example Scripts - WikiExcelChart (2017-07-21 - Version 0.4.0.1) - Download - General Help & Support - Example ScriptsOutlookEX (2021-11-16 - Version 1.7.0.0) - Download - General Help & Support - Example Scripts - WikiOutlookEX_GUI (2021-04-13 - Version 1.4.0.0) - DownloadOutlook Tools (2019-07-22 - Version 0.6.0.0) - Download - General Help & Support - WikiPowerPoint (2021-08-31 - Version 1.5.0.0) - Download - General Help & Support - Example Scripts - WikiTask Scheduler (NEW 2022-07-28 - Version 1.6.0.1) - Download - General Help & Support - Wiki Standard UDFs:Excel - Example Scripts - WikiWord - Wiki Tutorials:ADO - WikiWebDriver - Wiki Link to comment Share on other sites More sharing options...
Moderators JLogan3o13 Posted December 15, 2015 Moderators Share Posted December 15, 2015 @Radiance, do you need all four variables? In my mind, you're saying "If condition One exists, declare "w" and "x", but if condition Two exists, declare "y" and "z". Why can't you do that with just two vars? If condition Two is true, you're not going to use "w" and "x" right?Func _DoStuff($iParm) Switch $iParm Case 1 Local $sVar1 = "w", $sVar2 = "x" ; do stuff Return Case 2 Local $sVar1 = "y", $sVar2 = "z" ; do stuff Return EndSwitch EndFunc Radiance 1 "Profanity is the last vestige of the feeble mind.

BrewManNH Posted December 15, 2015 Share Posted December 15, 2015 Or do it the right way and declare both variables, and then set the values to them inside the switch statement. Func _DoStuff($iParm) Local $sVar1, $sVar2 Switch $iParm Case 1 $sVar1 = "w" $sVar2 = "x" ; do stuff Return Case 2 $sVar1 = "y" $sVar2 = "z" ; do stuff Return EndSwitch EndFuncConditionally declaring variables is a bad idea.
