Hi Selina,
On the question of ascii output files -The headers for ascii output
files are either turned on or off, but you can always write things to
the file before issuing a FILE/APPEND/NOHEADER command to output your
data. You can define symbols or strings and write them to the file,
with /NOHEADER, or you could use the Unix SPAWN command
yes? spawn echo " my first header line" > output.dat
yes? spawn echo " second header line >> output.dat
yes? list/noheader/append/file=output.dat/format=tab var1, var2
The date text you want can be created from the RETURN syntax,
`var,return=tstart` similar to what you are doing with the labels, as in
yes? spawn echo "start time is `var,return=tstart`" > output.dat
I'm not sure I understand all of what you're asking at the end of your
message about multiple dates, but maybe this'll get you started. You
can create variables

I was able to add the label to the gif file using the
information you supplied to my code I had it in the
incorrect place,however, I still have the question
about only removing the TIME header and adding my own
though Thank you for your help.

Hello Jaison,
I'm having a little difficulty creating my labels. I
want to be able to use the variable that is passed
to
the jnl file for setting the start and end time
labels
but I'm not sure of the syntax for example where $2
is
the variable that I want to obtain the start time
from:
let ts = "`$2,r=tstart`" ! starting time
Also the new labels aren't displaying here is my
code
! Parameter Order 1 2 3
! Usage: vis_draw_rect [monthly] [variable]
[landmap]
!1 1(monthly data), 0(nonmonthly data)
!2 variable
!3 1(draw land map), 0(no land map)
! define data viewport
define view/xlimits=0:1/ylimits=0.2:1 dataview
set view dataview
! obtain start and end time of the data so can
display
on the GIF
let ts = "Temp Text until get correct syntax"
if $1 then ! ver5.0 not allow brackets
SET MODE CALENDAR:MONTHS
endif
SHADE/SET/LEVELS=1/nokey/lev=(-99999) $2
!Remove Time from graph
go unlabel 4
PPL SHADE
!Add Start Time label
label `($PPL$XMIN1)*1.3`,12.5,-1,0,0.13 START DATE :
`ts`
SHADE/LEVELS=1/nolab/nokey/pal=black missing($2, 0)
SHADE/LEVELS=23/nolab/pal=default/key/over $2
! outline land map for PATHFINDER
if $3 then
go land black overlay
endif
Another question I had is for creating ASCII, TAB,
and
COMMA text files. The out put for TAB looks like
this:
VARIABLE : Analysis Temperature (Deg.
C)
DATA SET : SST 100KM GLOBAL
FILENAME : MY_Descriptor.des
FILEPATH : /DocRoot/User/www/product/
BAD FLAG : 999.9000
SUBSET : 361 by 141 points
(LONGITUDE-LATITUDE)

Is there any way to remove only the time instead of
the entire header through nohead?
TIME : 16-MAY-2005 00:00
and
---- L:1 T: 16-MAY-2005 00:00
I would like the header for a single date to look
like
the default but only have
START TIME: 16-MAY-2005 00:00
END TIME: 17-MAY-2005 00:00
and for files with muliple dates the header would be
the same but instead of this
---- L:1 T: 16-MAY-2005 00:00
I would like to have the following:
---- L:1 T: 16-MAY-2005 00:00 to 17-MAY-2005 00:00
Thank you for your time.
