Can I compare multiple variable values to 1 variable value in a clean way?

2022-05-03T09:54:10.504000Z

Just steer clear of writing "too compact" code and prefer readability over "performance". Usually "performance" isn't an issue nowadays (unless it is but then you should focus on low hanging fruit first).

Ah the funny thing is I am turning everything into Arrays anyways for other purposes! Reading through this there were a couple of new things I haven't seen, I looked them up and learned some new functions. I will probably end up doing something like the first example you gave. Thank you so much for your time and detailing. I am learning a lot from all the help!

You can build a list of pointers (or interfaces, if you use function blocks), and then batch process it.

VAR CONSTANT
    settingsNumber : UINT := 4;
END_VAR
VAR
    apSettings : ARRAY [1..settingsNumber] OF dut_Settings;
    i : __XWORD;
    xDoTask : BOOL;
    axDoTask : ARRAY [1..settingsNumber]; (* For option #2 *)
END_VAR

(* Initialization, somewhere *)
apSettings[0] := ADR(PVL.dut_PonyGroupSettings);
apSettings[1] := ADR(PVL.dut_MidGroupSettings);
apSettings[2] := ADR(PVL.dut_MainGroupSettings);
apSettings[3] := ADR(PVL.dut_HFGroupSettings);


(* Evaluation, perhaps somewhere else *)
(* Option #1 - very compact, not very readable *)
xDoTask := FALSE;
FOR i := 1 TO settingsNumber DO
    xDoTask S= (apSettings[i]^.ProcessVariable_ci = GVL.c_ai_DischargePressure);
END_FOR

(* Option #2 - "MapReduce" - less compact, a bit more readable (and perhaps useful if you need conditions later on *)
FOR i := 1 TO settingsNumber DO
    axDoTask[i] := (apSettings[i]^.ProcessVariable_ci = GVL.c_ai_DischargePressure);  // Map -> evaluate all the conditions separately
END_FOR

xDoTask := FALSE;
FOR i := 1 TO settingsNumber DO
    xDoTask S= axDoTask[i];  // Reduce
    // could also be written as xDoTask := xDoTask OR axDoTask[i];
END_FOR

This is less readable than yours, but is more flexible (it becomes more and more readable the more conditions you have).

I am sure you are busy, and I thanks for your help and your time good sir.

Don't worry, just don't use such code in your program ;-)

If you want your variable (Integer types only!) to be assessed against a value range, you could use a CASE OF Statement;

CASE MyUIntValue OF

    0 : ;
        // Do stuff
    1 : ;
        // Do more stuff
    2..100 ;
        // RANGE1

    100. 65000: ; 
        // RANGE2;
ELSE
    //anything 65001 .. 65535 go here
    ;
END_CASE

oh man i messed up, I edited my mistake

IF iVar1 = iVar10 OR
   iVar1 = iVar10 OR
   iVar1 = iVar10 OR
   iVar1 = iVar10 THEN

   DoTask := TRUE;

END_IF

Could be rewritten into;

   DoTask := (iVar1 = iVar10) ;

Albeit DoTask is now continously determined

Thank you kindly for your time I, I like the method you prescribe! But it sounds like its not possible to compare multiple variables collectively against one.

Maybe there was to much garbage, the variables being INT.

IF iVar1 = iVar10 OR
   iVar1 = iVar10 OR
   iVar1 = iVar10 OR
   iVar1 = iVar10 THEN

   DoTask := TRUE;

END_IF
