Hello, "Dot Deb"?

That's because you are trying to define a variable, "dat", with an intrinsic
function, "write", used to write the contents of a record to a filename, in
your case the "variable" to the file "output.txt". You should define
variables with operations, or other variables, or functions, or intrinsic
functions that give you a result (like "sublin"), ... etc.

If you have tryied the tutorial I suggest you ro read carefull the GRADS
User's Guide, specially the "GrADS Scripting Language" part.
