Thanks to all for the suggestions. For my purpose, that is, the purpose
of the end-user, anything short of a button on the same form would be
too "disconnected" to be really useful. However, these are all great
ideas for MY use while developing the code.
It is a truly wonderful thing to be able to sit at the same table with
all this talent!
Thanks again,
Dave

As several members have pointed out J is single threaded (in
particular the J GUI and Engine run in the same single thread). The
suggestions of semaphore and mapped files are perhaps more complicated
than what you required.
At the start of you run delete a known file (e.g.,
~temp\interrup_run). And then test for the existance of that file at
appropriate points in the running application (e.g., at the top of the
main loop). If the file exists you can then do whatever you want
within the application (e.g., use wd'mb ....' to put up a message
asking what the user wants to do).

Subject: [Jprogramming] Soft-stopping of a long loop
I have a loop that processes around a hundred files. Once started,
it must continue or, you must stop it using one of several ugly
methods from the operating system.
I put in the break. control word that looks at a variable to enable
a way to break out of the loop. I thought setting that variable with
a button on the form would be a good idea, but all I get when I try
this while the loop is running is the Windows "boink" . Is there a
good, or any, way to set this variable while the loop is running?
