Hello,

I have ARRAY [0..iReceivedData] OF BYTE where iReceivedData (UINT) is around 769 - depends on answer that is send by sensor. So i want to break up this array to more arrays. Is that possible? I want to break it where the value 32 is (that means space, so its space between the data parts). That is why i need to found value 32 in array and need to know its position. Anyone knows how to find that? so i will have aprox 30 arrays at the end and each represents specific information.

Hope someone has an idea.
Thank you.

to find "32", just use a for loop :

NbMaxSubArrays := UPPER_BOUND(ptArray,0);
// Clear pointer and length array
FOR index:=0 TO NbMaxSubArrays DO
   ptArray[index]:= 0;
   LengthArray[index]:=0;
END_FOR
// Fill pointer array
StartPosition := 0;
EndPosition := 0;
CurrentSubArray :=0;
FOR index:=0 TO iReceivedData DO
   // Only when we find the separator
   IF ByteArrayBuffer[index] = 32 THEN
      EndPosition := index;
      ptArray[CurrentSubArray ]:= ADR(ByteArrayBuffer[StartPosition]); // Pointer to the first byte
      LengthArray[CurrentSubArray ]:=EndPosition - StartPosition + 1; // Length of the array (count of elements)
      CurrentSubArray := CurrentSubArray  + 1; // Use next record in sub array we are saving those records in
      StartPosition := index + 1; // Update start position
      // protect overflowing pointer buffer
      IF CurrentSubArray > NbMaxSubArrays THEN 
         EXIT;
      END_IF
   END_IF
END_FOR

Unless you have to copy your data to save it from a change, I would just define pointers to every sub array. This will save memory and computations.

You can substitute 32 by 0 in all array. Afteer tath you can:

Str1 :pointer to string;

If pos[index]=0 then str1:=adr(arr[index+1]) end_if

Hello, Thank you i will try that.
I asumme that ptArrapt is pointer po my new array and ByteArrayBuffer is my data array?

Hello,

Thank you.
But i can not change 32 with 0 because i have also Nulls in my array that are important for me. but i can say pos[index] = 32, or? What is pos?

Pos would be your input array. I was thinking that your input array be an group of strings separated by number 32...

Sorry

You're assuming right.

Can anyone help define the VARS for this program?
I am a noob
