The script reads and prints data from a file which is located in the terminal local folder. Reading performs in the loop by the FileReadString() function until the end of the file. The FileIsEnding() function is used to check, if the end of the file is reached.

It should be noted that to define the end of the file, the function tries to read the next string from the file. If it doesn't exist, the function will return true, otherwise it will return false.
