Why does my MATLAB code not wait for UIIMPORT to complete?

I am using UIIMPORT. My code continues to execute before I have completed using the UIIMPORT wizard. However, I need to have the UIIMPORT variables available before the code continues.

To block code execution until the user has finished using the Import Wizard, request a return value from UIIMPORT. For example:
S=uiimport;
However, note that there is an additional bug in UIIMPORT that affects the return value method. This can be resolved using the following Related Answer:

Shawn,
The situation is like using load(): if you load() without assigning the value to anything then individual variables are created in your workspace, but if you assign load() to a variable then the result is a struct array that has one field for each variable that was loaded. In your situation you could use
drs_struct = uiimport('-file');
data = drs_struct.data;
