Get edges on axis

[Patrick Brockmann <brock@xxxxxxxxxxxxxxxxxx>]

Hi Ferreters,

Is there a way to get edges of an axis ?

Z[g=VAR] gives center of boxes
ZBOX[g=VAR] gives thickness of layers

Is there a ZEDGE ?

Thanks
Patrick

PS:
1) I cannot get them from the only two previous expressions
since I don't have the starting point of the edge.
2) What about GDT conventions, more explicite since you
have bounds_depth(depth,2) with
bounds_depth(depth,1) equal to upper limit and
bounds_depth(depth,2) equal to lower limit

Two exemples:

**********************************************************************
ZAXLEVITR = 0, 10, 20, 30, 50, 75, 100, 150, 200, 300, 400, 600, 800,
1000,
    1200, 1500, 2000, 3000, 4000, 5000 ;

 ZAXLEVITRedges = 0, 5, 15, 25, 40, 62.5, 87.5, 125, 175, 250, 350, 500,
700,
    900, 1100, 1350, 1750, 2500, 3500, 4500, 5000 ;

************************************************************************

ZWOCE = 0, 25, 50, 75, 100, 150, 200, 250, 300, 350, 400, 500, 600, 700,

    800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800,
1900,
    2000, 2100, 2200, 2300, 2400, 2500, 2600, 2700, 2800, 2900, 3000,
3100,
    3200, 3300, 3400, 3500, 3600, 3700, 3800, 3900, 4000, 4200, 4400,
4600,
    4800, 5000 ;

 ZWOCEedges = -12.5, 12.5, 37.5, 62.5, 87.5, 125, 175, 225, 275, 325,
375,
    450, 550, 650, 750, 850, 950, 1050, 1150, 1250, 1350, 1450, 1550,
1650,
    1750, 1850, 1950, 2050, 2150, 2250, 2350, 2450, 2550, 2650, 2750,
2850,
    2950, 3050, 3150, 3250, 3350, 3450, 3550, 3650, 3750, 3850, 3950,
4100,
    4300, 4500, 4700, 4900, 5100 ;

With the GDT convention, first example gives
************************************************************************

DEPTH = 0, 10, 20, 30, 50, 75, 100, 150, 200, 300, 400, 600, 800, 1000,
    1200, 1500, 2000, 3000, 4000, 5000 ;

BOUNDS_DEPTH =
  0, 5, 15, 25, 40, 62.5, 87.5, 125, 175, 250, 350, 500, 700, 900, 1100,

    1350, 1750, 2500, 3500, 4500,
  5, 15, 25, 40, 62.5, 87.5, 125, 175, 250, 350, 500, 700, 900, 1100,
1350,
    1750, 2500, 3500, 4500, 5000 ;
