>Assuming a user has Adobe Acrobat Reader installed on his system, how would you place a hyperlink to a PDF document on a menu dropdown?

Add item to a menu and call ShellExecute when it's selected by user.

DECLARE INTEGER ShellExecute IN shell32.dll ;
	INTEGER hndWin, ;
	STRING cAction, ;
	STRING cFileName, ;
	STRING cParams, ;
	STRING cDir, ;
	INTEGER nShowWin
lcPdfFileName = FULLPATH("mydoc.pdf")
ShellExecute(0, "Open", lcPdfFileName, "", "", 1)
