 ZERO 
 
 

Put the value zero (0.0) in the current buffer. Quite a destructive 
command !

 ZERO_QU 
 
 

ZERO_QU 0 or 1
	Controls the algorithm for INTEG 2D peak integration. When 
ZERO_QU is 0, normal integration is done, When 1, the amoeba is 
computed one the Absolute value of the data-set, and the integration 
is done over this amoeba in normal mode. Useful when integrating 
NOESY peaks with Zero-Quanta contribution. (Zero-quanta integrates 
to 0)

 ZM 
 
 

Creates a graphic box that permits to control the value of SCALE and 
the zoom state.
	To zoom in the display, simply click on the graphic window with 
the left and middle buttons pressed, and draw a rectangle on the 
display. You can redraw as many time as wished this rectangle. To 
zoom into the selected region, simply click in this rectangle with 
the left and right button of the mouse. You can also use the Zoom in 
and Zoom out buttons in the control box.
	The four little arrows can be used to move around the zoom 
region. Each arrow will move the selected region by half the size of 
the zoom box.
	There are five controls to adjust the vertical scale used for 
displaying the spectra. The Reset button will reset the display to 
the default, (ABSMAX 0 SCALE 1 ZOOM 0) where the largest peak in the 
screen in full size. The four other buttons permit to modify the 
scale value, raising or lowering the SCALE context by factor of 2 
and of 1.2.
	The ZM box also displays the coordinate of the cursor when a 
button is depressed, the unit used for display depends on UNIT

 ZNOT 
 
 

znot value
This context holds the focal length that will be used for computing 
a 3D display with the DISP3D/REF3D set of commands. A large value 
(1000) will produce a nearly orthometric projection, a small value 
(10 or less) will result in large conic distortions.

 ZOOM 
 
 

ZOOM n x1 y1  (1D) or  x1 x2 y1 y2  (2D)  or  x1 y1 x2 x3 y2 y3 (3D)

if n=0, zoom mode is off.
if n=1, zoom mode is on, you are then prompted for the coordinates 
(row,col) of the lower left point and upper right point for defining 
the 2D zoom window.
In 1D, you are only prompted for left and right borders. 
In 3D, you first do a 1D selection on one axis, and then a 2D 
selection on the orthogonal plane.
If a region was already selected on the display with the POINT 
command, this region is proposed as the default region.
