	Purpose:    Parse the item in the current dialog.  Must be a valid
		    integer or dxa in the given range.
	Method:     - Get the text string.
		    - Try parse as "".
		    - Try parse as string of all spaces
		    - Parse as a int/dxa (generic error if can't).
		    - Test for ".5".
		    - Compare with min and max.
		    - Try parse as "Auto".
		    - If out of bounds, use id to put up specific error
		      (with strings of min and max as parameters).
	Returns:    The return value may be used as a boolean or as a word.
		    fFalse (0) -> not parsed
		    wNormal (1) -> parsed normally
		    wBlank (2) -> parsed a null line
					   (*pw is valNil)
		    wAuto (4) -> parsed as "Auto" (*pw is 0)
		    wSpaces (16) -> parsed a line of all
					   spaces (*pw is valNil)

		    !fDxa only:
		    wDouble (8) -> parsed with ".5" trailing

	Note:	     The interval [wMin..wMax] is closed.
	Note:	     Return value is doubld the parsed value when wDouble.
	Note:	     When wDouble, 2*wMin and 2*wMax must be valid ints.
	Note:	     Numbers ending in .5 may have no trailing spaces.
	History:
	     6/18/86:	 Adapted for trailing kanji spaces --- yxy
	    07/03/85:	 Added wSpaces return
	    10/23/84:	 Fixed wAuto to return with *pw == 0.
	    10/ 5/84:	 Added ut parameter.
	    10/ 5/84:	 Added wMask and combined dxa and w parsing.
	     9/26/84:	 Created.
