You don't give very much information about your grid, but suppose you  
have an (x,y,z) grid of a variable TEMP. Then:

define symbol zplot 450							! to plot at 450m depth
shade/nolab/lev=($zplot) temp
! ....... put a centered label 0.5 inches above the plot box
label/nou `($ppl$xlen)/2` `($ppl$ylen)+.5` 0 0 .2 Map of TEMP at  
($zplot) meters

Of course you can do this by hand (i.e. just put your depth value in  
these commands directly), but defining the symbol ZPLOT lets you make  
a script that ensures that the label matches the plot command. That  
is, put the above commands into a simple script:

cat > tempmap.jnl
define symbol zplot $1						! to plot at passed argument $1
shade/nolab/lev=($zplot) temp
! ....... put a centered label 0.5 inches above the plot box
label/nou `($ppl$xlen)/2` `($ppl$ylen)+.5` 0 0 .2 Map of TEMP at  
($zplot) meters
Ctl-d

Now, in Ferret:

go tempmap 450

Or even simpler:

cat > tempmap.jnl
shade/nolab/lev=$1 temp
! ....... put a centered label 0.5 inches above the plot box
label/nou `($ppl$xlen)/2` `($ppl$ylen)+.5` 0 0 .2 Map of TEMP at $1  
meters
Ctl-d
