If you have an object associated with it by calling it using:

DO FORM linesform NAME Olines LINKED
*--Now release it from somewhere else
IF UPPER(TYPE('olines'))="O" .AND. Olines<>.NULL.
   	Olines.VISIBLE=.F.
   	Olines.RELEASE()
ELSE
   	Olines=.NULL.
   	RELEASE Olines
ENDIF

Or you can step through all of the current active forms and do something similar to:

* Release myform by stepping through all forms
clear
LOCAL llFound, loForm
llFound=.F.
FOR EACH loForm IN _SCREEN.FORMS
	IF UPPER(ALLTRIM(loForm.CAPTION))='MYFORM'
		llFound=.T.
		loform.release()
		? 'Found caption myform and closed it'
		EXIT
	ENDIF
	IF UPPER(ALLTRIM(loForm.name))='MYFORM'
		llFound=.t.
		loform.release()
		? 'Found name of myform and closed it'
		EXIT
	ENDIF
ENDFOR
RETURN

For the dos window you can

run /N <your pkzip command>

or create a batch file that contains the pkzip command line in it and following that command line in the batch file add an exit and then run the batch file instead.
