In Scilab 5.5.2, when using the meof(f) function, the command window freezes. What is the problem?

Question

Mathematics

I wrote the following listing in SkiNotes:

f=mopen('C:\TEK0000.txt');
i=0;
while ~meof(f) do
i=i+1;
end
mclose(f);

I press F5 (Save and execute) and the command window freezes. What is the reason and how to get rid of freezing?
