Using Substring With An Array

Question

Again I cannot see what I am doing wrong. Is this another bug or am I using the array incorrectly? This works
 DefineArray($TestArray,2) $SearchString = "aaaa" $TestArray[1] = "&lt;aaaa&gt;&lt;bbbb&gt;&lt;cccc&gt;" if($SearchString = SubString($TestArray[1],1,4)) Print("Correct") endif

This Dont
 if($SearchString = SubString($TestArray[1],1,IndexOf($TestArray[1],"&gt;&lt;")))

You have one too many closing brackets in this line...
 if($SearchString = SubString($TestArray[1],1,4)))

Edit never mind you fixed it...

@RichardR I tried to simplify the expression, and didn't remove the extra closing bracket. But when I did simplify it, it did work.

Still have the issue with the IndexOf with in the expression

If I use a variable in the expression it works.
 DefineArray($TestArray,2) $SearchString = "aaaa" $TestArray[1] = "" $TestIndex = IndexOf( $TestArray[1],1,"><" ) -1 if($SearchString = SubString($TestArray[1],1,$TestIndex)) Print("Correct") endif

@rz90208 EZ-Script is good for simple scripts, and i believe it was developed for simple statements. there are no expression trees or byte code translation the script lines/statements are evaluated on the fly using a text parser and the things can get complicated with nested conditions, multiples arguments, operators etc. with that in mind you have some options: 1) Simplify the expressions like using variables, remember everything is evaluated on the fly so replace multiple function calls assigning the function result to a variable and reusing the variable to check the result. 2) Avoid nested expressions 3) Avoid complex scripts when possible OR 1) Learn c# and create a plugin 2) use the DJ's Javascript plugin: https://synthiam.com/redirect/legacy?table=plugin&id=224 the plugin uses a Javascript Interpreter for .NET (Jint) https://github.com/sebastienros/jint Is not fast as c# code but it's well known, and if you find a language/parser issue you can open a ticket.

Thanks ptp, I did just that and simplified the script using variables. It is not easy to build even a simple brain and not write complex scripts. I do know some JavaScript, would be nice to have a script manager for js as we do for ez-script. Thanks again for your reply.

This code works perfect
 definearray($testarray, 2) $searchstring = "aaaa" $testarray[1] = "" IF ($searchString = substring($testarray[1], 1, 4)) print("correct") ENDIF

And so does this, by adding spaces (for some reason) with proper code formatting
 DefineArray($TestArray,2) $SearchString = "aaaa" $TestArray[1] = "" if($SearchString = SubString($TestArray[1], 1, IndexOf($TestArray[1], "><"))) Print("Correct") endif

If you wish to use javascript, use the javascript plugin from here: https://synthiam.com/redirect/legacy?table=plugin&id=224

@DJ, To help troubleshoot:
 DefineArray($ArrayOfStrings,2) $ArrayOfStrings[0] = "foo;bar;baz" $SearchString = "foo" #this works $index1=IndexOf($ArrayOfStrings[0],";" ) if($SearchString=SubString($ArrayOfStrings[0],0,$index1,";" )) print("1: starts with foo" ) endif #this works too $String1=$ArrayOfStrings[0] if($SearchString=SubString($String1,0,IndexOf($String1,";" ))) print("2: starts with foo" ) endif #The code below works with a space before the IndexOf if($SearchString=SubString($ArrayOfStrings[0],0, IndexOf($ArrayOfStrings[0],";" ) )) print("3: starts with foo" ) endif #The code below does not work #Error on line 24: Variable is an array: $ArrayOfStrings if($SearchString=SubString($ArrayOfStrings[0],0,IndexOf($ArrayOfStrings[0],";" ))) print("4: starts with foo" ) endif

EDIT: I've changed the code with several combinations, a space before the IndexOf does the trick

Okay - i fixed it for next release. There was a goof in the regex

Thank you again DJ. My son tells me to start using JavaScript also, but I love using ez-script it is so EZ and powerful. Thank you also ptp
