Re: LIST command

[Jaison Kurian <jaison@xxxxxxxxxxxxxxxxxx>]

Hi Emilie,
                Hope all you want is to include the information about the 
pressure level along with the data. Here is an example....

 suppose the dimension is along depth axis ie Z-axis
 ( for simplicity /file=filename is dropped from list command)

 yes? define axis/z=50:500:50  pres  
 yes? let temp = Z[gz=pres]/-10  ! variable with 1d grid
 yes? list temp                  ! without format
             VARIABLE : Z[GZ=PRES]/-10
             SUBSET   : 10 points (Z)
 50    /  1:  -5.00
 100   /  2: -10.00
 150   /  3: -15.00
 200   /  4: -20.00
 250   /  5: -25.00
 300   /  6: -30.00
 350   /  7: -35.00
 400   /  8: -40.00
 450   /  9: -45.00
 500   / 10: -50.00
yes? list/format=(2f7.2)  Z[gz=pres],temp ! with format , for pressure 
                                          ! level values you have to 
					  ! specify the grid
             Z: 25 to 525
 Column  1: Z is Z (axis PRES)
 Column  2: TEMP is Z[GZ=PRES]/-10
  50.00  -5.00
 100.00 -10.00
 150.00 -15.00
 200.00 -20.00
 250.00 -25.00
 300.00 -30.00
 350.00 -35.00
 400.00 -40.00
 450.00 -45.00
 500.00 -50.00

 Since you had used 'i' along with 'temp' it seems your dimension(1D)
 is along abstract axis I ( ie. coordinate axis X) in that case

 list/format(2f7.2) X[gx=temp], temp

Hope this helps

With regards 

Jaison
