tried creating a matrix straight forward but couldn't (on control pallete--->array and matrix) and then type letter a. it didn't work.

try, however, to create a 2dimension array of strings. you do this by function pallete --> initialize array click on the bottom part of the array and extend it so you have two index. wire a 6 to the two dimension input.

then just conect a string constant to the "element" entry and you have created an array of strings.

hope this helps!

please tell me if it does. (or doesn't)

Do what was stated above and just create an array. You can then right click the array indicator on your block diagram and create a property node for blinking. Set the value for blinking to be true. This, however, will make your entire array blink. You will have to look at how to reference just the row or column that you want because I am not exactly sure.

I don't think that it can be done with the control/indicator's properties. There is a property that would appear to flash an individual element, but I can't see anyway to determine which element. I figured there might be a way to index which one, and from that the rest of the column or row but ...

Does it have to blink? if not you can just highlight the rows/columns you want.

Feels kind of lame, but uses only native controls and avoids the "Blinking" property which kind of bugs me. Basic idea: Hide two boolean arrays behind the string array, futz with sizing then use the booleans to flash the row or column. Can't help but think I'd use the picture control if I weren't just messing around.
