## Description

TryStrToDate tries to convert the string S to a TDateTime date value, and stores the date in Value. The Date must consist of 1 to three digits, separated by the DateSeparator character. If two numbers are given, they are supposed to form the day and month of the current year. If only one number is given, it is supposed to represent the day of the current month. (This is not supported in Delphi)

The order of the digits (y/m/d, m/d/y, d/m/y) is determined from the ShortDateFormat variable.

The function returns True if the string contained a valid date indication, False otherwise.
