Re: [ferret_users] Title label variable help

[Selina Satterfield <satterfields2000@xxxxxxxxx>]

Thank you for your help on the GIF label issue I was
able to find the correct location and display the new
labels. 

Now I am having some problems when writing my own
header. Currently I need to be able to create ASCII
text, COMMA delimited text and tab delimited text.

For the comma and tab delimited text I use list/nohead
as advised and then display the my own start and end
date labels. The problem I have is now I need to
recreate the whole header myself because the only item
I really wanted to keep from displaying was the TIME
header. 

Here is an example of the original header
             VARIABLE : Average Gradient (Deg. C/100
Km)
             DATA SET : SST 100KM GLOBAL
             FILENAME : MY_Descriptor.des
             FILEPATH : /HTML/DocRoot/www/product/6/
             BAD FLAG :   999.9000    
             SUBSET   : 361 by 141 points
(LONGITUDE-LATITUDE)
             TIME     : 16-MAY-2005 00:00


This is how I want the new header

VARIABLE : Average Gradient (Deg. C/100 Km)
             DATA SET : SST 100KM GLOBAL
             FILENAME : MY_Descriptor.des
             FILEPATH : /HTML/DocRoot/www/product/6/
             BAD FLAG :   999.9000    
             SUBSET   : 361 by 141 points
(LONGITUDE-LATITUDE)
             START DATE : 16-MAY-2005 00:00
             END DATE   : 17-MAY-2005 00:00

I was able to recreate most of the header by using
return values such as title,dset ,dsetpath, bad, and
units. I am having trouble creating the exact output
for subset. Also I haven't been able to output the
information for DATA SET. I thought that the return
value of DSETTITLE would have this information but it
returns an error (I am using Ferret v5.41 for AIX ).

Another issue I have with the comma and tab delimited
files is when multiple dates are used the following is
displayed for each date
 ---- L:1 T:   16-MAY-2005 00:00
Is there any way to modify that header?

The final issue is concerned with creating ASCII files
orignal go file used the
HEADING=ENHANCED/FORMAT=(5G12.5) which displays the
following:
VARIABLE : Average Gradient (Deg. C/100 Km)
             DATA SET : SST 100KM GLOBAL
             FILENAME : MY_Descriptor.des
             FILEPATH : /HTML/DocRoot/www/product/9/
             LONGITUDE: 154W to 150W
             LATITUDE : 63S to 42N
             TIME     : 16-MAY-2005 00:00
             GEOMETRY: XY 
             SIZE:  5  106  
             FORTRAN FORMAT: (5G12.5)
             MISSING VALUES FLAG:   999.9000

X COORDINATES: degrees_east
 206.00      207.00  . . . .
Y COORDINATES: degrees_north
 -63.000     -62.000 . . . .
DATA:
  .10000      .10000      .20000   . . .

When I use the NOHEAD to strip the header and create
my own header it removes the X COORDINATES, Y
COORDINATES sections and only displays the data
without the DATA: header. Is there any way that I can
recreate these sections? Thank you for your time and
all of the help.
