Creating DDS Specifications
In order to transfer field-oriented data, like that found in spreadsheets
or databases, you must create a template that tells the AS/400 where each
field begins and ends, and what type of data will be in each field. This
is done with DDS specs or F&I specs. See Appendix D for a detailed
explanation of creating F&I specs. The PDM utility on the AS/400 is used
to create the DDS.
In this example you will see how to create DDS specs that allow a PC file
to be transferred and properly formatted on the AS/400. The PC file is
called SAMPLE and was created using a PC spreadsheet application. The PC
spreadsheet file is represented in Figure C-1 shown below. This
spreadsheet contains four fields. Table C-1, at the bottom of this page,
describes how you will define each field.
