Jim,
Looks like you found a solution, but here is this if you are interested at all. This is pretty basic.
John

lcFile = GETFILE()
l_OpenWin( lcFile )



FUNCTION l_openwin
PARAMETERS tcOpenMe

  DECLARE INTEGER ShellExecute ;
    IN SHELL32.dll ;
    INTEGER nWinHandle, ;
    STRING cOperation, ;
    STRING cFileName, ;
    STRING cParameters, ;
    STRING cDirectory, ;
    INTEGER nShowWindow

  DECLARE INTEGER FindWindow ;
    IN WIN32API ;
    STRING cNull, ;
    STRING cWinName
          
  ShellExecute(FindWindow(0, _SCREEN.caption), ;
    "Open", tcOpenMe, ;
    "", SYS(2023), 1)
