Append to a string indicator

Hi there,
I have a normal application. i need to display the test status to
the user during test, and the new test status will append to the
next line of the same string indicator that i previously used.

Anyone know how to do that ?

I tried using a local variable of the string indicator , but whenever i write
a new
string into it, the previous string will be deleted. I need to see the previous

string as well.

Ex: Test 1 Pass
Test 2 Pass
:
:
keep on updating the test status

Hi Antony

1 - Make sure the string indicator is a multiline string.
2 - Store the current displayed string in a shift register and on every loop pass the data from the input to the output of the
shift register.
3 - Use an invisable string local or a global to store the latest test state only.
4 - Inside your loop check if the latest test state, global or local, has changed.
5 - If the latest test state has changed, append the data to the data stored in the shift register and display in your multiline
string indicator.

I have brushed over a bit of detail but I hope it helps.

Anthony,
have you tried using the local variable as the first input
to the 'Concatenate Strings' vi ?
