RSDAT Conversion Routine
Use
Converts a date in an external format into the internal format.
Features
First, the system tries to convert the date in accordance with the user settings (). If the system cannot perform the conversion in this way, it automatically tries to identify the format.
Valid formats:
DD.MM:YYYY
MM/DD/YYYY
MM-DD-YYYY
YYYY.MM.DD
YYYY/MM/DD
YYYY-MM-DD
For automatic recognition, the year has to be in four-digit format. If the date is specified as 14.4.72, this is not unique and can cause errors.
Example
Conversion from an external format into an internal format:
4/14/1972 → 19720414
