| Description |
If the current string has not been exhausted, the next sequence of characters are returned as a string as far as either a carriage return : Chr(13), line-feed : Chr(10) or both, or the end of the string are encountered. The carriage return and line feed characters are not returned in the string.
After returning the string, the read position in the string is moved to the character after the carriage return or line-feed or last character of the string, as appropriate.
A Nil string is returned if there are no more characters to return.
