Hello everyone!

I'm giving this script-making thing a spin and have ran into a problem. I'd like to have the script generate a map based on coordinates. The end result is to have "floating" weather maps for tropical cyclones.

I see a map making command in the DA Manual: MAKE,lat,long,zoom,width,height

I've tried both of the following lines...

Either line yields the following error: Floating point division by zero

Would somebody be so kind to square me away?

Zoom is the width of the map in statute miles. Width and height are the map sizes in pixels. Offsetx and Offsety refer to the displacement of the map contents from center (should normally be 0), and aspect ratio refer to the distortion in the X or Y direction (should normally be 1). Example command:
