Hi, I have a textfile vi here which will log the date & time once when the input changes to 1. However, i wish to modify the vi to the following requirements. After the textfile reaches a certain number of lines or after 24 hours, it will close the current textfile and create another textfile with the date as the file name. I've tried to use 'get number of records' but found that it will only get the number of characters in my textfile instead of the number of lines. if anyone have any example related to my requirements or knows the way to do it, please kindly help me. Thanks.

It's really not that big a deal to see if it's a new day. You can use a couple different functions to get the date and you just have to check to see if the date changes. Attached is one method. If you decide to use an actual timestamp instead of a string, all of the comparison functions work with timestamps.
