Adam,
It is not clear what version of MATLAB you are using and whether you are
working under GUIDE or not. In either case, you need to assign march.m to be
the <callback> field of the <DEMO> object. If you use GUIDE, you will need
to override the default callback function.
You need to assign some arbitrary callback to <PLAY> and then fetch the text
using e.g.
<my_value>=get(handles.<textbox>,'String'>
