How to remove or delete line in a string indicator?

[Mr.7]

I have a string indicator that receives data continuously. If the number of lines in the indicator becomes 100 then on receiving a new line after 100th line the very 1st line will be removed and so on..in simple words i need to maintain only the latest/last 100 lines received in the indicator. How would i do this? Kindly help me out.

Hi SriKrishna,

I have few questions,

how do i find the number of lines in a string indicator? is there any property or do we need to create a design to find out the count of lines with the help of end of line constant?

Also when the number of lines becomes 100, on receiving a new line only the 1st line has to be deleted/removed not all the lines. 100+1 - 1st line =100

100+2 - 1st & 2nd line = 100 etc...

Latest 100 lines have to be maintained on the display.

Thanks for your time,

Regards,

Arvinth
