*******************
If CTRL-C is treated as a normal keystroke, what can I do to abort the script 
if say, the script has a programming mistake that has an infinite number of 
pause?

*******************************
However,  a short script 

more off
for i=1:5000; rand(5000,5000), end
disp('Outside for loop')

Execute the above and press Ctrl+C while for loop is active. 
Ctrl+C aborts the loop and do not go disp('Outside for loop'). 

This behavior is what the original author perhaps expects, I think.

Ctrl-C issue discussed in other places are not simple 
and it is not an issue of keystroke but an issue of treating interrupt.
