You could use the GETOBJECT() function - if it fails, then it wasn't already open. The GETOBJECT() will throw an "Operation unavailable" error if VFP is not already started.

e.g., from a one file app I have tested this with..

LOCAL loVFP, llErr
ON ERROR llErr = .T.
loVFP = GETOBJECT(,"VisualFoxPro.Application")
IF !llErr
   MESSAGEBOX("VFP started.")
ELSE
   MESSAGEBOX("VFP not started.")
ENDIF
ON ERROR
RELE ALL
