Escaping from a loop in Acad 2012

[petervose]

When I have previously been stuck in a loop, or one of my routines freezes I have been able to get back to the Command Line by hitting escape (the harder the better).  Now, in 2012 I get a message asking whether I'd like to Quit the Program, or allow it to continue to run.  If I quit the program AutoCAD shuts down and I lose evertything, and if I allow it to continue It'll never end..  Anyone know of any other key combination equivalent to the old faithfull 'Escape'.?

I was stuck in a WHILE loop many times during development.

I was also stuck a few times in a dialog that was supposed to go

away, and then come back after selecting objects on the screen.

In both instances I had to terminate AutoCAD because [Esc]

was not the answer. I never did try the [Break] key...

Looks like you need to clean up the program(s):

 - Ensure user input is of the correct type (STRING, REAL, LIST, etc.),

 - Ensure the user input is what the program asks for,

 - Provide a default value if the user input is not correct,

 - Provide default value(s) before gathering user input, or

 - Terminate the program before entering a loop.

If one pauses inside the loop, test the input before further

execution or test the user input as part of the loop condition.

For this second half of the above sentence:

Get User Input

WHILE (test User Input)

 Execute

 Get User Input

);WHILE

The answer is always the easy part.

It's foolproofing the question that is the hard part.
