This limit applies when your TI process is performing actions such as assigning a value to a variable or importing individual records of data. Any value or record longer than 8000 single-byte characters is truncated.
For example, if you are importing lines of data from a text file, each line of text can be no more than 8000 characters long. If you are importing data from a comma delimited file, each record in the file can be no more than 8000 characters long.
