This is a PPWIZARD command line switch.
Sometimes you may wish to process most files with a few exceptions, this switch allows you to specify those exceptions. The switch may be used as many times as required.
ppwizard *.IT /Exclude:TEST*.IT /Exclude:TRY?.IT /Output:OUT\*.html
If you filter out all input masks such that PPWIZARD has no files to process then by default an error is generated, to alter this use the /0OK switch.
