To run production concatenates, you'll need to customize its behavior by creating a PFF file. You can then use the PFF file as a command line parameter in DOS or in a Windows icon for CSConcat.exe (the associated filename of this utility). For example, if you name your PFF MyConcat.pff, then you can run the concatenation program by invoking:
"C:\Program Files (x86)\CSPro 7.2\CSConcat.exe" MyConcat.pff
This assumes that CSPro was installed in the default directory. Your PFF file must have a .pff extension.
You can create a PFF file in one of two ways: either  create it yourself using a text editor (such as Notepad or Wordpad), or  simply run CSConcat once, and a PFF file will be automatically created for you—it will always be called CSConcat.pff, and it will be placed in the same folder as your output data file.
The following section shows the options available to you in a CSConcat PFF file. A PFF file is not case sensitive, so you can use any combination of upper and lower case text.
The [Run Information] block is required and must appear exactly as shown in the example above.
The [Files] block is required and names the file(s) to be concatenated and the output data file. At a minimum, you must name one input file and one output file. Of course if you only name one input file the concatenation operation will essentially be just a file copy.
The [Parameters] block is optional. ViewListing determines whether the .lst file is viewed. There are three options:
- ViewListing=Always means you will always see the generated listing file.
- ViewListing=Never means you will never see the generated listing file.
- ViewListing=OnError means you will see the generated listing file only if an error(s) occurred during the run.
If the ViewListing entry is missing, the default action will be Always.
ViewResults determines whether or not the concatenated file(s) are displayed with TextViewer at the end of the run. The available choices are Yes or No. If the ViewResults entry is missing, the resultant data file will be displayed.
ConcatMethod sets the concatenation method to use. There are two options:
- ConcatMethod=Case means use case concatenation mode, skipping invalid and duplicate cases.
- ConcatMethod=Text means use content concatenation mode, appending files regardless of contents.
When using ConcatMethod=Case, a data dictionary must be specified via an InputDict entry in the [Files] section. If ConcatMethod is not specified in the PFF file, the default action will be Text.
