ShortCut(`MSPaintApp',`pbrush.exe',0x9320,0,`Sorry')

According to Help Workshop

"If you need to include a topic ID, but do not want to send the program any messages, you can either use -1 for the wParam argument and 0 for the lParam argument, or you can simply include the commas without specifying the values for the arguments as follows:"

ShortCut(class_name, myapp, , , topic-ID)

I have included a Topic_ID to display (Sorry) if the program is unavailable. This topic will appear as a popup window and can be a friendly message if the program is not available from the help file.
