<div class="markdown_content"><p>yes that why example is declared in the VAR list<br/> VAR<br/> example:INT;<br/> END_VAR</p> <p>but this will be done automatic when you type in the program.</p></div>

<div class="markdown_content"><p>Thanks Shooter </p> <p>One thing, how do you determin which case is used. How can you choose case 1. or 2. or 3. I presume if you declare your variable "example" as an interger you can feed values in that variable, then choose each case you want.</p></div>

<div class="markdown_content"><p>If example is 1 case1 will be executed<br/> It will not even test if example is 2 but will move to the end_case instruction just because the example is not correct for any other.<br/> This is also not allowed so<br/> 1:<br/> and 1..3: is not allowed.<br/> btw it must be a colon and not a comma.<br/> see example i gave you <br/> CASE INT1 OF<br/> 1, 5: BOOL1 := TRUE;<br/> BOOL3 := FALSE;<br/> 2: BOOL2 := FALSE;<br/> BOOL3 := TRUE;<br/> 10..20: BOOL1 := TRUE;<br/> BOOL3:= TRUE;<br/> ELSE<br/> BOOL1 := NOT BOOL1;<br/> BOOL2 := BOOL1 OR BOOL2;<br/> END_CASE;</p> <p>if int1 is not 1,2,5,10,11,12,13,14,15,16,17,18,19,20 else will be done<br/> otherwise <br/> when it is 1 or 5 bool1 will be true <br/> when int1 is 2 bool2 will be false<br/> if int1 is from 10 to 20 bool3 will be true<br/> etc.</p></div>

<div class="markdown_content"><p>Will this be the case with multiple cases? e.g.<br/> CASE Example OF<br/> 1.case1();<br/> 2.case2();<br/> 3.case3();</p> <p>END_CASE;</p> <p>Say if case1 executes its code, will it automatically jump to the next or as you said jump to end case.</p></div>

<div class="markdown_content"><p>When the CASE is done the program jumps to END_CASE</p></div>

<div class="markdown_content"><p>Hi, very simple question. if i have code in a case and no jump address. Will the code keep executing over and over again?</p></div>
