dtaus - Converter for DTAUS files
The dtaus(1) program reads and writes German DTAUS files. DTAUS is an
semi-acronym for DatenTrägerAUStausch. It is used by German credit
institutes in order to implement money exchanges between accounts and
credit institutes. These files are always called DTAUS0.TXT.
Since they are shipped in a weird ascii format that is not quite
readable and writable for human beings a special control format was
invented. The dtaus(1) program reads and writes such a control file
and generates a proper DTAUS file if requested or decodes one.
The control file implements a very simple format which was invented
only for use with the dtaus(1) program. Like with many *nix
configuration files empty lines and those beginning with a hash mark
(‘‘#’’) are ignored. The remaining file is splitted into three major
parts: one BEGIN record (representing the A record), several regular
records (representing C records) and one optional END record
(representing the E record), which is ignored when the control file is
read but is extracted from the bank file if one is decoded.
Here’s a short sample for a control file:
Name Martin Schulze
Name Martha Schulze
Zweck Gebühr Wohnheimnetz
Text Anschluß u. 11+12.97
Please note that several field names are used in both the BEGIN and the
regular record. When used in the BEGIN record they denote your name
and your bank account. When used in a regular record they are
affiliated with your customers data.
You may use up to 15 fields entitled as Text. They will be recorded
one by one and stored into additional data records using the same
order. This way you could add a detailed description of the type of
money transfer if you like. The contents of the field Zweck are most
probably what the customer will see on their bank statements.
The field Ausfuehrung is optional and denotes the day when the entire
transaction should be processed. The date has to be given as
DD.MM.YYYY and will be translated into the resulting bank file
literally. It may not be younger than the creation date of the file
which will automatically be inserted by dtaus(1). The processing date
also may not be more than 15 years later than the creation date.
Explanation of type
One of the following:
LK Lastschrift Kundenseitig
GK Gutschrift Kundenseitig
LB Lastschrift Bankseitig
GB Gutschrift Bankseitig
Explanation of transaction
One of the following:
Vermögenswirksame Leistung mit Sparzulage. Als Argument kann
das Jahr angegeben werden, für das diese Leistung gilt. Wenn es
weggelassen, wird, verwendet dtaus das aktuelle Jahr. Vom Jahr
wird nur die letzte Ziffer verwendet, es muß daher auch nicht
vollständig angegeben werden.
Wie Vermgen, jedoch ohne Umlaut.
E-Cash Lastschrift aus Verfügung im elecctronic Cash-System
Lastschrift aus Verfügung im elecctronic Cash-System mit
You may only use one of these for the entire file. You are not allowed
to switch between Einzug and Gutschrift within the same file. If you
require the credit institute to process both types, you’ll have to
provide two separate diskettes.
Support for Euro
From January 1st 2002 the currency in many European countries, Germany
is among these, changes to Euro. Hence, money transfer changes from DM
(formerly known as ‘‘Deutsche Mark’’) to Euro. The format
specification of DTAUS was meant for DM but was modified in 2001 to
support Euro as well. The current version of dtaus(1) supports both
currencies. It defaults to using Euro, however. To switch to DM,
simply add the keyword DM (or Euro respectively if this version was
compiled without Euro support as default) to the BEGIN record. If no
currency keyword is given, the compiled in decides (upstream source
defaults to Euro).
German Umlauts are converted into two 7-bit characters on the fly so
you don’t need to care about them. Since the DTAUS0.TXT file only uses
uppercase letters every text is also converted to uppercase.
Except for the way records are delimited the format should be self
DTAUS files use a special but simple and publically documented format.
It is included in the distribution of dtaus(1) as dtaus.txt.
