The use of Throw( in scripting

I  use Throw() in my programs to stop the execution for that particular part of the program. This still works in JMP 13 but I sometimes get a new window with a JMP Alert.  I can't seem to simulate the problem - It happens in a User Window - the program sees a problem, the program sends a Caption and executes a Throw().  In earlier version I only got the Caption now I sometimes get an Alert window as well.  I thought Throw() just stops execution. I can use text in the Throw("Hello") and it will in this case get a JMP Alert with the text - if executed on its own I get only the text in the log.  I'm not sure what to expect when.  Can anybody help.

The same is true for Throw(

Another thing about stop().  It seems to only stop the script in the displaybox that holds it.

dt = open("$SAMPLE_DATA\Big Class.jmp");
newwindow("x", <<MODAL></MODAL>

Thanks Craige - exactly what I need - the Stop() function.  I can't get it the Sctipt Manual though.

I would expect that the 'throw' button in your example would display an empty Alert like below.  This is what I get in my own program - as you said it is in an interactive environment

Alert dialog triggered by JSL throw in Interactive modeAlert dialog triggered by JSL throw in Interactive modeAlert dialog triggered by JSL throw in Interactive mode

When JSL runs from a button script it is running in interactive mode and produces alert dialogs when JMP thinks you should know what happened. If you run a script by submitting it, JSL runs in batch mode and just sends alerts to the log. I think in your case you probably want to use stop() rather than throw("msg").

When you submit this script, it runs in batch mode and brings up a window. When you click a button in the window, the button script runs interactively.

newwindow("x",
buttonbox("throw(err msg)",setscript(print(1);throw("this is an error message");print(2))),
buttonbox("throw",setscript(print(3);throw();print(4))),
buttonbox("stop",setscript(print(5);stop();print(6))), 
)

For each of the buttons, only the first number is printed in the log because the script stops.
