[gembud] FL -3 Cannot create file error with gdtopo

To whom it may concern,

I am trying to create a .gem file using gdtopo and I get the following
error:

[FL -3] Cannot create file topography4.gem

Do you know what is going on and how to resolve this issue?

Attached is my script.  Thank you for your time.
