I would recomend to use ShellExecute

PROCEDURE help
DECLARE INTEGER ShellExecute IN shell32.dll ;
	INTEGER hndWin, ;
	STRING cAction, ;
	STRING cFileName, ;
	STRING cParams, ;
	STRING cDir, ;
	INTEGER nShowWin
lcHelpFileName = FULLPATH("help.htm")
ShellExecute(0, "Open", lcHelpFileName, "", "", 1)
RETURN

Even better, you can use VFP built-in help system with SET HELP command in which case you wouldn't need ON KEY LABEL.
