reverse netCDF {dimension, coordinate variable}?

Is there NCL API to reverse a dimension? I know I can do this with
NCO:ncpdq. What I mean:

I want to reverse the order of the members of the dimension=ilev in the
following:

printVarSummary(z_int_var)
; Variable: z_int_var
...
; Dimensions and sizes: [ilev | 57] x [lat | 21] x [lon | 30]
; Coordinates:
; ilev: [1.650789985433221..1000]
; lat: [59.68421052631579..21.78947368421052]
; lon: [-130..-57.5]
...
z_int_var_dims = dimsizes(z_int_var)
ilev_min = 0
ilev_max = z_int_var_dims(0)-1
lat_min = 0
lat_max = z_int_var_dims(1)-1
lon_min = 0
lon_max = z_int_var_dims(2)-1
; do [top,bot] for [SW,NW,NE,SE]
print(z_int_var(ilev_min,lat_min,lon_min))
; (0) 43899.82
print(z_int_var(ilev_max,lat_min,lon_min))
; (0) 1157.416

But, for each (lat,lon), z_int_var(ilev,lat,lon) should increase
directly with ilev, not inversely.
