Re: [ferret_users] Title label variable help

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi Selina,
That might be easiest, to do the last bit of editing outside Ferret  in your c++ (I think sed is commonly included as part of Unix, so it still might be an option).  ASCII output from Ferret is designed to have all the information available to you, but it is not set up to be flexible in all possible ways

You can use the lengths of the strings to create format statements that'll align the text

  let len = strlen(ut1)
  list/file=temp.txt/nohead/format=(8X,A`len`)/APPEND ut1

  let len = strlen(dt1)
  list/file=temp.txt/nohead/format=(8x,A`len)/APPEND dt1 

  ...

And, rather than making a string bf1 containing the bad flag, use a FORMAT statement to write out the numeric value with the format that you want:

  ...
  let bf = `variable, return=bad`
  list/file=temp.txt/nohead/format=(8x,"BAD FLAG : ", f8.4)/APPEND bf

Thanks Ansley, 

I will probably have to just do the switch in my C++
code since I can't use third party tools other than
ferret. 
I have successfully re-created all the headers for
COMMA and TAB formats. Is there any way to align all
of this information. I tried passing the value for
STRLEN in to the format command, but it ended up
cutting off the header.

Here is what my out put looks like:
         VARIABLE : Average Gradient Deg. C/100 Km
             DATA SET : SST 100KM GLOBAL
           FILENAME : MY_Descriptor.des
             FILEPATH : /HTML/www/product/1
                        BAD FLAG : 999.9
               TIME : 16-MAY-2005 00:00 to 17-MAY-2005
00:00
 
I would like to have the first letter in each line to
line up like this:

     VARIABLE : Average Gradient Deg. C/100 Km
     DATA SET : SST 100KM GLOBAL
     FILENAME : MY_Descriptor.des
     FILEPATH : /HTML/VisUser/www/product/1
     BAD FLAG : 999.9
     TIME : 16-MAY-2005 00:00 to 17-MAY-2005 00:00

list/file=temp.txt/nohead/format=(A50)/APPEND ut1
list/file=temp.txt/nohead/format=(A40)/APPEND dt1 
list/file=temp.txt/nohead/format=(A40)/APPEND fn1 
list/file=temp.txt/nohead/format=(A70)/APPEND fp1
list/file=temp.txt/nohead/format=(A40)/APPEND bf1

Also is there anyway to set the precision. For example
I would like BAD FLAG to be set to 999.9000

I tried adding the precision option however it didn't
change.
list/PRECISION=8/file=temp.txt/nohead/format=(A40)/APPEND
bf1


Thanks again.

Hi Selina,
Ferret does not have a way to restore the coordinate
labels that are 
removed with /NOHEAD.  I wonder if you might want to
leave the header 
and use a tool like sed afterwards to edit the time
label.  A spawn 
command from Ferret could do this from your script
so that the editing 
would always occur when you create the file.

The only issue that I have left now is being able
      

to
    

display the Coordinate headers that are removed
      

from
    

ASCII files when using LIST/NOHEAD

For example the following X Y and T COORDINATES
X COORDINATES: degrees_east
 134.00      135.00      136.00      137.00     
138.00    
 139.00      140.00      141.00      142.00     
143.00    
Y COORDINATES: degrees_north
-46.000     -45.000     -44.000     -43.000    
-42.000    
-41.000     -40.000     -39.000     -38.000    
-37.000    
DATA:
....

I could probably do this with my C++ code as well,
however if ferret already has a way of doing this I
would rather use that route.

Again Thank you Jaison, Martin and Ansley for all
      

of
    

your help.
