Hi Keren,<br>
<br>
Another possibility is that you haven't displayed a variable yet,
thus you don't have plotting dimensions defined. If you open
"dummy.ctl" and then don't display anything, I think your "q w2xy"
line will return "No scaling environment", then this will cause
"xloc" and "yloc" to be improperly defined. Try display something
first from your file "dummy.ctl".<br>
<br>
Also, it helps to use the "say" function to display these variables
within your script to help diagnose the problem. For example,
adding say xloc', 'yloc will print these values to the screen.<br>

You have a lot of extra spaces floating around in your
commands. As far as I know, when you're inserting script
variables into a command in a grads script, you need to be
very explicit with the formatting of the command. In other
words, the spaces around your 'lat', 'lon', 'xloc', and
'yloc' may be causing the syntax error. I recommend
removing those spaces and trying again. For example,
change<br>
<br>
"draw mark "flag " "xloc " "yloc " 0.1"
<br>
<br>
</div>
into <br>
<br>
</div>
"draw mark "flag" "xloc" "yloc" 0.1"<br>

The error tells you what the problem is. You must
have a "draw mark" command somewhere in your
script that has a syntax error in it. You can use
the grads documentation index to determine values
of the various arguments to that function. I
suspect you have an error in your x and y
arguments in the function call. The x and y
arguments need to be in real page units, not world
coordinates. You'll need to use the 'query
(position)' functions to translate between world
coordinates, grid coordinates, and page
coordinates. A commonly used one is 'q w2xy',
which would convert world coordinates to real page
coordinates.<span><font color="#888888"><br>
