Is this the entire script? I think you will need to first open a<br>
file and display something. This will set the scaling environment<br>
in the display. As the script is, your query statement is likely<br>
not returning a number but an error, e.g.,<br>
<br>
'q w2xy 'lon1' 'lat1<br>
<br>
returns:<br>
"No scaling environment"<br>
<br>
and thus lon1 is set to "environment". Try to open a data<br>
set first, set the lat/lon/time/alt, display a variable, then run<br>
your script below.<br>
