Well, exit'' takes J down completely. I have read through most of the foreigns again, and through doc, and I searched the messages from this forum for a bit. Either I can't find the right search string or it has not been discussed since I have begun following this. I just can't find an answer.
I have a deeply embedded function that discovers that it has completed the task set before it. (This is a continuation of my solitare game solver). I am doing trial solutions - and if everything works. it will declare a solution and end. This function was not part of the initial design. It would be inconvenient for me to return and then set a flag so that the top level solver code emits the right messages, although I could do that. Instead I was hoping to, from whatever level of recursion I have reached is doing trial solutions, to decide that I have met the burden of "being done". and simply return to the console prompt, allowing the stack to be thrown away. I suppose I could execute the entire thing under a try. and throw back to it. Is throw the only way to do this? I guess I could just use an uncaught throw, as: foo =: 3 : 'if. y > 64 do. y throw. else. foo >: y end. ' foo 1 $ foo 1 # foo 1 Is the answer as simple as an uncaught throw or is there a "right" way? I searched for "uncaught throw" and found uncaught throw. gives no message Now it does: error code 35, 'uncaught throw.'

I don't want to mess with the debugger. I guess I could make a master catcher that runs everything but then I have to pass on errors or I get nothing when I have a bug. I'll admit I am being lazy. I am trying to add trial and error to a solver that works whenever there is enough info in the puzzle specification, but when there is not, the next trick is to try blocks in various positions, and when you get impossible progressions, you can eliminate a space and then try again. I might be descended through several layers as the solution is found. -- Of course I can ride in the carpool lane, officer.
