PDFX is A-Shell's "print to PDF file" subsystem, which consists of an entire set of GDI printing directives related to producing and post-processing PDF files. All of these commands begin with "//PDFX," followed by a key and then a value. For example, the following command tells PDFX to overwrite the existing file if it exists:

//PDFX,Save.When.Exists,1

The most common function of PDFX is to produce PDF documents such as invoices and automatically email them to clients. PDFX includes a variety of email-related commands for that purpose.

The PDFX subsystem is documented in a separate help file which you can access from the A-Shell downloads...documents page. Contact MicroSabio if you have questions or would like to add PDFX to your A-Shell license.
