Greetings All

I get this error message when I try and run an m file that creates another m
file with an equation in it.

Example:  I use one m file to create another m file called test.m that has
the equation in it "y=vert*sin(24);"
then I try and run it I get

>>> run('/home/rat/Documents/octave/eq_research/aa/test.m') 
error: run: file must exist and be a valid Octave script file
>>>error: called from:
error:   /usr/share/octave/3.2.3/m/miscellaneous/run.m at line 46, column 2

The m file does exist it is created using the fprintf(fid) commands.  I
notice that If I open the m file that is created (test.m) and add a space and
delete the space then save it the command will work does anyone know of a
better work around then opening each created m file.  It's as though the file
is created but it cant see it.  Does anyone have a work around

here's my version
