Concatenating string and putting in shift register slows computer down

Hi all,

 

I was trying to create a record of comms between LabVIEW and an Arduino by concatenating the current message with previous messages and putting it in a shift register.  After a couple of hours the LabVIEW started to crawl.

 

I had a vague idea that you could write to a string indicator without wiping the old contents.  I thought if I could do that there would not be a huge overhead copying an every larger string.  

 

Am I dreaming?

 

Thanks
