When masking multi-record type fixed width files, the path to the
definition files is created by prefixing each filedef name with
the filedefdir and suffixing it with dm.txt. For example (using
the connection file below): c:\sdmmapper\flatdefs\RV000.dm.txt
The first filedef in the list can specify options which
apply to the whole file - HEADER, TRAILER, DATEQUOTED, CHARQUOTED, LINETERM or
NULLIND.
Note:
None of the options above can be specified in other filedefs. For
multi-format masking, all record definitions must have DELIM=FIXED specified.
A record type is identified by the RECTYPE
parameter on the first line, for example,
RECTYPE=01_SAZART_X3:”000”. This parameter names a field
within the record and gives a literal value which must be matched for that
record type to apply. Field definitions consist of the field name, length and,
optionally, a field datatype (Date or Numeric, not case sensitive) and mask
value (a mask is assumed to be a date unless show to be something else). The
field definition must follow the format below:
04_ERSTELLDATUM_D10, 10, Date:"DD.MM.YYYY"
Where 04_ERSTELLDATUM_D10 is the field name, which is 10
bytes long and contains a date in the format "DD.MM.YYYY"
Note:
A datatype must be followed by a colon and mask value in double
quotations.
