Match pattern bug

Solved!
Go to solution

Hi:

 

I have a vi that just looks for strings in strings, and its not working as expected.   I am wondering if there is a bug with the "match pattern" tool.  It's very simple and attached.  Can someone see if they can duplicate the error and if they can find a solution?  No other vi's are required.

 

The error:

 

Watch the value of the boolean for the label "Is the DC Supply at ddress 7 a 6632B?"  Its default value is "false" but when the first string array element is processed it turns to "TRUE" which is what is expected.  The bug is that the "TRUE" value is not preserved in the next iteration of the loop and it should be.

 

 

Thanks.

Found the problem.  The shift register was not wired up correctly.
