    linmsg will do what you want. It operates on the righmost
    dimension of an array

    Pls look at the examples: specifically 3 and 4

    [1] get data array x(:,:,:)
    [2] *if* dimensions are not named then
        name each dimension
        x!0 = "time"
        x!1 = "lat"
        x!2 = "lon"
        
    [3] use dimension reordering
        
        xNew = x(lat|:,lon|:,time|:)
        xNew = linmsg(xNew, opt) ; (lat,lon,time)
        x = xNew(time|:,lat|:,lon|:)

    If you have not done so, pls look at the following.
    If possible, use color and in duplex mode but
    it looks fine in black and white.
