to pass parameters to an exe you use ParamStr(n) and ParamCount (use delphi help).
If you don't want to use DOS command prompt to pass the parameters use a shortcut, and then right click, and add your parameters in the target (target: C:\xx\xxx.exe -x xx.pdf)

another way to do what you want is to read the file name from an ini file, or (for what i think you should do) use OpenDialog class (windows standard window for opening files)

Hope this helps.
